Posted by John Hayden on | Comments Off on How to Control your Device with Flow Restrictor Orifices
What are Flow Restrictor Orifices and how do they work?
Orifice restrictors are flow control devices placed in the line of a pneumatic device that regulates the amount of air passing through it. They are used when a fixed flow rate is required because they cannot be adjusted. By controlling the flow rate, a flow restrictor orifice can be used to control and maintain the speed of a pneumatic device or fluidic process.
How to Control your Device with Orifice Restrictors
In this video, John Hayden uses Air Logic precision molded orifices to control the speed of the Model Corliss Engine. The miniature precision orifices in this video range from .025″ to .040″. Several flow restrictors are tested to find the best orifice size to achieve the technical specifications of the Corliss Engine. The orifice diameters are color-coded based on the flow restriction each precision orifice provides.
Every application is special and requires the right size orifice. Too large of an orifice and the flow rate will be too high, resulting in an over-speed condition. Too small of an orifice and the flow rate will be too low, resulting in an under-speed condition. It is important to select the right orifice size for each application to ensure optimal performance. In the video, a .025″ orifice provides a very low RPM, and a .040″ orifice provides the right amount of airflow for the Corliss engine to work at its rated output.
What are the benefits of using an Orifice Restrictor?
Orifice restrictors are a low-cost alternative to variable flow rate devices. They are less expensive and easier to use than variable flow rate devices, and they provide a fixed flow rate. This makes orifice restrictors an ideal choice for high-volume device manufacturing. Having a reliable method of flow control that is also cost-effective is often one of the application requirements during product design.
Another benefit of using orifice restrictors is that they can help to improve the accuracy and consistency of pneumatic devices. When a fixed flow rate is required, orifice restrictors can help to ensure that the speed of the pneumatic device is consistent from start to finish. This is an important aspect of product design when considering large-scale production. This is especially true if the device is built by a third party and quality control is critical.
How to specify an Orifice Restrictor by Orifice Diameter
When selecting an orifice restrictor for a device, it is important to consider the flow control needs of the device. The size of the orifice restrictor must be matched to the flow rate of the device in order to achieve optimal performance. This can be achieved through calculation or Bench testing. See this video for a bench testing method.
Orifice diameter is the most important factor to consider when selecting an orifice restrictor. The orifice diameter must be matched to the size of the device in order to achieve optimal flow control. Selecting the wrong orifice diameter can result in poor flow control performance and inaccurate device operation.
There are many additional factors that impact the flow restriction of an orifice, not just the orifice diameter. The length and shape of the orifice also play a role in the flow control properties. Long orifices provide more resistance to airflow than short orifices, and sharp-edged orifices provide more resistance to airflow than round orifices. A Precision orifice must control these additional factors to provide flow control in a tight tolerance band.
Can you use a Precision orifice for Flow control of Liquids and Gases?
Flow restrictors can be used to impart flow control on air, gas, or liquids. When a fluid flows through an orifice, the velocity of the fluid is restricted. This results in a decrease in the flow rate of the fluid. The size of the orifice affects the flow rate of the fluid, as well as other factors such as the length and shape of the orifice. Flow restrictors provide the best flow control when the flow rate hits the critical velocity.
The difference in fluid flow performance through a flow restrictor with gas and liquid is the compressibility of the fluid. Flow rates of a non-compressible fluid will plateau after the critical velocity is achieved. With gas, the flow control properties of a flow restrictor are somewhat limited by the compressibility of the gas. So, in both operating conditions, the orifice will regulate flow. However, since gas is compressible, the flow data will continue to rise with increasing pressure, even after the critical velocity has been achieved. In other words, pressure changes will result in small flow measurement changes above the critical velocity.
Orifice Restrictor vs Flow restrictors
Flow restrictors are a general term for any device that restricts the flow of a fluid. They can be fixed or variable and may be controlled mechanically or electronically. Flow restrictors are used in a variety of applications, from controlling the flow rate of pneumatic devices to regulating the flow of liquids.
One common type of flow restrictor is the orifice restrictor. Orifice restrictors are small devices that are placed in the line of a pneumatic device to control the airflow. They are used when a fixed flow rate is required, and cannot be adjusted.
Miniature precision orifices generally have under .040″ orifice diameter. The provided flow control is intended for very low flow rates. Flow control applications for miniature precision orifices are typically table-top size devices or smaller. Precision metering in a small system is one of the flow control applications where a miniature precision orifice is commonly used.
In this video, John Hayden describes the basic needs of a system to control flow rate.
What are some other names for Orifice Restrictors?
Orifice restrictors are also commonly referred to as flow restrictors orifice, flow control orifice, precision orifices, and airflow restrictors. All of these terms refer to the same device: a small device placed in the line of a pneumatic device that regulates the amount of air passing through it. By controlling the flow rate, orifice restrictors can be used to control and maintain the speed of a pneumatic device.

Posted by John Hayden on | Comments Off on Pneumatic Switch 101 | Pressure & Vacuum Switches
Pneumatic switches use air to actuate, or open and close, circuits. The pneumatic switch sends air through a tube to flip a switch and activate or deactivate attached circuitry. At Air Logic, we specialize in developing and supplying pneumatic switches such as pressure and vacuum switches. Learn more about how these two switch types operate, their applications, and our available selection of options.
What Are Pressure Switches?
Pneumatic pressure switches activate an electrical contact once pre-established pressure levels are present within fluid systems. Once enough pressure acts on the switch, it will flip and close an attached circuit to turn a device or function on. When pressure levels drop, the switch will open the circuit and turn off the device. Pressurized fluid systems with set pressure thresholds, such as circuits for lights, pumps, HVAC systems, solenoids, and valves, commonly use these switches.
How Pressure Switches Work
Pressure switches rely on changes in pressure to actuate. When pressure on the switch’s diaphragm increases, it starts to compress a spring. That spring is calibrated to compress only beyond a certain pressure rating, or the setpoint. Once the spring tenses or compresses beyond that point, the switch will flip. Pressure switches can either close normally open (NO) electric contacts or open normally closed (NC) contacts.
Pressure Switches From Air Logic
At Air Logic, we manufacture pressure switches to integrate with a wide variety of pneumatic systems. We build each of our switches for optimal reliability, with every design capable of managing at least 1,000,000 cycles without failure. Our switches use subminiature designs so they can fit into tight or compact spaces, and they’re also compatible with different sterilization options because they are ozone- and gamma radiation-safe. Other pressure switch options and features we provide include:
Electrical ratings from 0.1-25 amps
Factory preset options
Pressure set point ranges of 0-15 psi, 0-30 psi, 0-60 psi, and 0-100 psi
Flush, manifold, panel, and pipe thread mounting styles
Vacuum Switches
Pneumatic fluid systems can also use vacuum switches. They respond to vacuum pressure or negative pressure, levels to actuate. These switches are useful in environments where a vacuum holds liquids or gases; they can passively monitor vacuum pressures and open or close circuits based on any pressure changes.
How Vacuum Switches Work
Once the switch registers a change in the negative pressure based on the preset sensitivity of the setpoint, the diaphragm of the switch will open or close the attached circuit, turning off or powering on a device. Vacuum switches can be used with NO and NC states.
Vacuum Switches From Air Logic
At Air Logic, we design vacuum switches that are versatile and built to last. We test each switch design to ensure it can provide fail-proof functionality through at least 1,000,000 cycles. Our team also designs them to be ozone- and gamma radiation-safe for sterilization purposes. Choose from these options and specifications for your vacuum switches:
Electrical ratings from 0.1-25 amps
Factory preset options
Pressure set point ranges of 0-5 inHG, 0-10 inHG, and 0-28 inHG
Flush, manifold, panel, or pipe thread mounting styles

Posted by John Hayden on | Comments Off on Pressure Relief Valves
Hydraulic and pneumatic systems must regulate air or liquid pressure according to a constant pressure threshold. If the pressure exceeds the set level, it can damage equipment and create a safety hazard for workers. Pressure relief valves regulate pressure levels to prevent these dangers.
Learn how pressure relief valves work, their benefits and applications, and other important considerations when choosing a valve for your system.
What Are Pressure Relief Valves?
Pressure relief valves (PRVs), or back pressure regulators, reduce system pressure when it exceeds a maximum threshold. PRVs can also reduce pressure peaks that could damage equipment elsewhere in the facility. The main components of a pressure relief valve are:
Diaphragm
Spring-loaded mechanism
Nozzle
When the pressure in the hose or pipe exceeds the pressure limit, will push against the diaphragm, compress the spring and open the valve. The valve opens and closes to maintain the specified pressure level. When the pressure dips below the accepted threshold, the valve closes. With adjustable PRVs, operators can adjust the spring mechanism to collapse under a higher or lower amount of pressure.
Pressure Relief Valve Benefits and Applications
Click to Expand
Pressure relief valves offer the following benefits:
Enhances safety: PRVs were invented as a result of boilers exploding when they were not properly monitored. Thus, they are an easy and effective way to keep your system safe.
Increases efficiency: Relief valves automatically reclose when the pressure lowers to the set level, preventing excess loss of expensive gases from the system.
Protects system components: By regulating the pressure in your system, PRVs protect downstream components from damage that might otherwise result from pressure pulses.
Reliable: Critical facilities rely on pressure relief valves to release excess pressure that could damage the system.
Versatile: PRVs are versatile enough to fit in a variety of systems.
Pressure relief valves are essential in the following applications:
Medical beds
Blood pressure cuffs
In conjunction with non-relieving regulators
Specifications and Considerations of Pressure Relief Valves
Before selecting a pressure relief valve for your application, consider the following product specifications:
Adjustment range
Inside diameter of the tubing
Barb size
Outlet port: vent to atmosphere or another tubing
These general considerations are also important to note before committing to a particular PRV:
Relief pressure: Estimate the maximum amount of pressure that will be released from the process flow.
Adjustable or preset: Preset PRVs cannot be altered according to changing pressure needs, but adjustable models can accommodate these demands.
Flow requirements: Factor in the maximum flow rate, flow variables, and port configurations of the relief valve.
Type of fluid or gas: Choose a valve with a body type and seal material that fits your particular process fluid or gas.
Size and weight: Consider the valve material, mounting option, and thread sizes when positioning the PRV in your system.
Materials: Most valves are made of plastic, brass, aluminum, or stainless steel. Weigh each material’s compatibility, advantages, and disadvantages relative to your system’s needs.
Operating temperature: Make sure the valve you choose can handle the expected operating temperature of your application, as the temperature can affect flow capacity and the responsiveness of the spring mechanism.

Posted by John Hayden on | Comments Off on Relieving vs. Non-Relieving Regulators
Pressure regulators are available in two types: relieving and non-relieving. Both can give the maximum volume of flow needed while keeping outlet pressure constant. The difference between relieving and non-relieving regulators depends on whether they self-release or trap excess pressure. At Air Logic, we offer both relieving and non-relieving pressure regulators that can be either preset or adjustable.
Here we explain the features and common applications for relieving and non-relieving regulators to help you choose the right one for your project.
Click to Expand
Relieving Regulator
A relieving regulator releases excess pressure through a relief valve, a hole in the middle of the diaphragm. When air pressure exceeds the acceptable limit of a system, the relieving regulator opens a vent to allow the air to escape. A hissing sound usually indicates the release of air. There is no need to add an extra relief valve to the flow system since the relieving regulator performs this function on its own.
Non-Relieving Regulator
A non-relieving regulator restricts airflow once it exceeds the setpoint. There’s no vent path in a non-relieving regulator so the gas stays in the system. These regulators require extra care because they can become dangerous if excess pressure builds up without being released. In a closed system, it is important to have a relief valve downstream. Alternatively, an open system design should be implemented downstream of the regulator to prevent the build-up of excessive pressure.
Non-relieving regulators are most beneficial when dealing with hazardous or expensive gases. By trapping these gases for safe or controlled release, operators ensure the safety and efficiency of the entire facility.
Applications for Relieving & Non-Relieving Regulators
It’s important to choose the best type of regulator for your application. Here are a few recommendations for each regulator’s best use cases.
Relieving Regulator
Relieving pressure regulators are typically used to power pneumatic systems, such as:
Air tools
Small medical devices
Actuators
Spraying equipment
Blow-off nozzles
Non-Relieving Regulator
Non-relieving regulators are used for preventing dangerous or expensive gases and fluids from escaping in these settings:
Inert gas (i.e. nitrogen) applications
Gas tanks
Valuable gas
Propane fuel
Oxygen tanks
Relieving & Non-Relieving Regulator Solutions from Air Logic
Knowing the difference between a relieving and non-relieving regulator will help you make an informed decision for your application. Air Logic produces a vast selection of pneumatic equipment and control components, including relieving and non-relieving regulators.
Posted by John Hayden on | Comments Off on Precision Air Regulators
Air Logic designs and fabricates vacuum and pneumatic control components. Our precision air regulators provide optimal pressure regulation to low flow systems where setpoint accuracy is required. They provide a stable output pressure despite changes to pressure and flow upstream. Learn more about the features, benefits, and applications of precision air regulators as well as the precision pressure regulators we offer.
What Is a Precision Air Regulator?
A precision air regulator is a device that delivers precise and reliable air pressure to sensitive instruments. They are favored for industrial, lab, and OEM applications. Precision air regulators typically help reduce downstream pressures to acceptable levels by stabilizing the force applied to cylinders.
Pressure regulators rely on the following three elements:
Restrictive element: A stem or spring-loaded valve seat for reducing device pressure
Sensing element: A piston or diaphragm for detecting device pressure
Reference force element: A top spring for adjusting device pressure in PSI
These three elements begin working together when the reference force opens the valve. The sensing element detects the pressure from the valve and closes it enough to maintain the desired PSI. Unlike ordinary pressure regulators, precision pressure regulators utilize a steady bleed of air consumption that allows the pressure to be much more accurate and replicable.
Air Logic Precision Air Regulator Features and Applications
Air Logic’s precision air regulators provide several advantages over other pressure regulators. Our precision regulators maintain consistent pressure regulation, providing stable pressure and greater reliability. For example, a 10 PSI change in supply pressure will only result in a 0.1 PSI output pressure change. If the supply pressure is interrupted, the regulator will adjust to maintain accurate output pressure within 0.1 PSI.
Our precision air regulators also rely on a 20-turn adjustment for better accuracy in setting pressure. Clients can customize each product’s adjustment range and style, but all are compact enough to save space in any facility.
Various industries and applications rely on precision air regulators, including:
Air over liquid systems
Gas analyzers
Automation integration
HVAC
Test equipment
Smokestack analyzers
Pharmaceutical equipment
Laboratory equipment
Medical equipment
Calibration stands

Posted by John Hayden on | Comments Off on The Lord’s Prayer on the Point of a Pin
The following is a transcription of a story that still lives on and gets told at our company to this day.
In 1935, Fred Knapp engraved 286 characters that make up the Lord’s Prayer on an area equal to the point of a pin. This dramatic illustration demonstrated the extreme accuracy of a George Gorton Engraving machine.
The head of an average pin is approximately 100 thousandths of an inch, 0.100″, in diameter. The point of an average pin is 5 thousandths of an inch, 0.005″, in diameter or 20 times smaller. The entire Lord’s Prayer would have to fit in a circle no wider than two human hairs.
The first step was to engrave the Lord’s Prayer in the proper design and size suitable for reduction. This was done with the aid of a standard George Gorton copy type. The resulting master had the lord’s prayer engraved in a two-inch circle.
The next step involved polishing the surface to be engraved. Flatness to within one hundred thousandth of an inch (.00001″) was necessary to produce a legible engraving.
The engraving operation had to be performed by the very point of the cutter. Vibration, temperature changes, dust, and even the weight of Mr. Knapp’s hand on the feed mechanism was sufficient to distort the minute letters of the finished engraving.
The finished lettering requires a magnification of about 175 times to read. For inspection of the lettering during the engraving process, however, a small power glass was used. The cutter operating directly above the engraving made it necessary to mount the glass at an angle to see the work. Consequently, the field of view was so small that only one line at a time could be focused.
The result of this meticulous preparation is the complete Lord’s Prayer, consisting of 286 characters, engraved on the end of a platinum-gold alloy wire within a circle of 0.005″ diameter. Using the same size letters, the entire Bible of approximately 2,750,000 characters could be engraved within an area of 1/2″ x 3/8″.
Posted by John Hayden on | Comments Off on Wetted Materials in Water Treatment
“Wetted materials” specifications are found in devices that have specific requirements due to the process media. When reviewing wetted materials, it is essential to understand your application’s requirements. Wetted parts should be able to withstand the temperatures, chemicals, and regulations they will come in contact with throughout the span of their intended application.
What are Wetted Materials?
Wetted materials are parts of a component, like a valve or a regulator, that make contact with the liquids, gas, or air that flows through the device. In a simple valve, wetted materials include the body, spring, and seal materials, or any other part that gets wet by the process media. This excludes materials used on the outside of products, such as labels or inks.
Typical Applications of Wetted Materials
Wetted materials are required in a wide variety of applications including:
Pipes and related products
Mechanical plumbing devices
Water filters and treatment units
Among these, one of the more common applications is drinking water and water treatment.
Drinking-Water Filters & Water Treatment
Drinking-water filters are part of most water treatment systems and they remove silt, sand, dirt, and sediments from your water. Some of the most common applications for drinking water filters include:
Reverse Osmosis
Reverse osmosis is a water purification system that uses a semi-permeable membrane to eliminate unwanted particles and minerals like dirt, salt, fluorine, cryptosporidium, and chlorine from drinking water. It also removes microorganisms, cleaning water down to a molecular level.
Under-Sink Filters
Under-sink filters work in the same way as reverse osmosis. However, they do not eliminate minerals like fluoride and calcium. Under-sink filtration systems filter high volumes of water, don’t take up counter space, and don’t produce wastewater.
Ultraviolet Purification
UV purification is the most effective way to destroy pathogens without altering the water taste. It uses ultraviolet rays to scramble the DNA of disease-causing organisms in the water, rendering them inert and unable to replicate to cause illness. UV purification is an excellent alternative to chemically treated water.
Countertop
Countertop filtration devices eliminate chlorine, fluoride, lead, pesticides, and other contaminants and minerals from water. It is a cost-efficient option that produces clean, better-tasting water.
Portable Gravity
Portable gravity filters are ideal for removing pathogens that cause E. coli, typhoid, and cholera from water. Thanks to their effectiveness and small size, these filters are widely used by the world’s major emergency relief and aid organizations in field operations.
Bottleless Water Coolers
These filters take water directly from the tap eliminating the need for plastic bottles. Because tap water is more regulated than bottled water, dispensing directly from the tap is more reliable and higher quality than using bottled water.

Posted by John Hayden on | Comments Off on Orifices for Flow Control | Orifice Restrictors
Orifices control the flow of gas, air, and liquid through a variety of systems, from Ventilators to Coffee Makers. They are available in a wide range of diameters, materials, and configurations to meet the particular needs of various liquid and airflow control applications.
What are Orifices and Why Use Them?
Orifices, also known as flow restrictors or orifice restrictors, or fixed volumetric flow control, control the flow of gases or fluids through a system. The diameter of these devices maintains a constant flow rate through the system in which it is installed. The placement and size of an orifice determine its particular use, but they are most commonly used to restrict material flow and monitor and control flow rates in industries ranging from aerospace to medical.
The Importance of Flow Control
Flow control is critical for the safe and efficient operation of industrial and manufacturing equipment in various industries. Pneumatic and hydraulic systems in particular use orifices to ensure optimal pressure control and flow without the need for manual regulation and recalibration. By determining the correct diameter and shape of your orifice, they can carefully monitor and control system flow rates and gauge flow stream additives to ensure outputs are consistent, precise, and predictable.
Get the Best Orifice for Your Flow Control Needs
To ensure optimal flow regulation for your operation, Air Logic offers a variety of flow control solutions. Our extensive selection of flow orifices includes a range of designs, sizes, and materials.
Orifice Types
Our comprehensive portfolio of orifices includes molded, filtered, and threaded orifices, as well as a selection of directional flow control valves.
As Air Logic’s most popular design, molded orifices offer the simplest method of flow control. Each orifice is easily identifiable, with color-coded diameter sizes for optimal flow restriction. Our molded orifices are precision molded, assembled, and tested in the US. They are available in polysulfone, polypropylene, and polycarbonate materials, and can be customized to meet your particular application requirements.
Our filtered orifices incorporate an integrated filter into precision-molded orifices to reduce upstream contamination in a variety of applications. Our filtered orifices are comprised of polysulfone Housing and orifice with a Stainless Steel Mesh filter with a variety of customization options.
For ease of installation, Air Logic’s threaded orifices are second to none in the industry. With an incorporated threaded fitting, you can install the orifice directly into the pipeline for a simple and secure flow control method. Our threaded orifices are available in polysulfone materials and can be customized to your needs.
Directional flow control valves use orifice technology to control flow in one direction and provide full flow in the opposite direction. The orifice acts as the only path for material flow. The directional flow controls automatically move depending on the direction of the flow. In one direction, the flow will push the disk into an unrestricted position. In the opposite direction, the disk will move and force the flow through an orifice. Our directional flow orifices are available in nylon, polysulfone, silicone, and stainless steel.
Material Selection
It is important to consider which material is best for your application. Since orifices are installed in many different applications, chemical compatibility and temperature resistance are critical. For this reason, Air Logic typically uses polysulfone or polypropylene polymers.
Both polysulfone and polypropylene are valued for their chemical resistance and exceptional stability under pressure and high temperatures. They do not oxidize or rust, which makes them especially useful for pneumatic equipment. With exceptional chemical resistance, polysulfone and polypropylene orifices are more durable and longer-lasting than other materials. Less wear and corrosion means fewer part replacements and equipment failures, which greatly reduces your maintenance and repair costs.
At Air Logic, we understand that standard orifice sizes are not always the best option for every application. That’s why we offer molded orifices in custom sizes. Using quality mated molds, we can manufacture quality custom orifices to meet your exact flow control needs.
Our custom orifice sizing abilities include:
Molded nominal orifice diameter sizes from 0.004″ to .040″
EAU 10,000+
Cv range from 0.00038 to 0.04
Standard flow tolerance range of +/- 4%”
sLPM range from 120 to 12,500 (ref @ 9 psi)
Contact Our Experts for Premium Flow Control Solutions
Since 1975, Air Logic has provided innovative flow control products for customers around the world.
