Orifice Restrictors are the simplest method of flow control and are one of Air Logic's best-selling product lines. Also called Precision Orifices or Flow Restrictors, they work on the principle of flow restriction by orifice diameter. The size is identified in the part number and by color codes assigned to each specific dimension. In addition to orifice diameter, Air Logic controls many smaller factors that have an impact on the total restriction of the orifice.

Filtered orifice restrictors build on Air Logic's orifice product line with the additional protection of an integrated filter. Orifices work on the principle of Flow Restriction with the orifice diameter being identified in the part number and by color codes assigned to each orifice size. In addition to orifice diameter, Air Logic controls many smaller factors that have an impact on the total restriction of the orifice. This is why Air Logic's orifices are trusted to provide accurate and reliable flow performance across a variety of different markets. All of the Air Logics products are precision molded, assembled, and tested in America. Filtration immediately upstream of the orifice will protect the orifice in case of system contamination.

Directional Flow Controls apply orifice technology in one flow direction and free flow in the other. They work on the principal of Flow Restriction with the orifice diameter being identified in the part number. In addition to orifice diameter, Air Logic controls many smaller factors that have an impact on the total restriction of the orifice. A moving disk changes position based on the flow in the circuit. In the controlled direction, the orifice is the only path the media can flow through. In the opposite direction, the disk moves and the media is free to flow through the product unrestricted. 

Threaded orifices integrate one of Air Logic's best-selling product lines, orifice restrictors, with a threaded fitting to reduce system complexity. They work on the principle of Flow Restriction with the orifice diameter being identified in the part number. In addition to orifice diameter, Air Logic controls many smaller factors that have an impact on the total restriction of the orifice. This is why Air Logic's orifices are trusted to provide accurate and reliable flow performance across a variety of different markets. All of the Air Logics products are precision molded, assembled, and tested in America. 

Metal Needle Valves are an adjustable method of flow control. Internally, the pin and body create an adjustable orifice that restricts flow. Useful for instances when the exact flow rate hasn't been determined or to compensate for flow variation in other parts of the system. Very fine threads ensure adjustment accuracy. A nylon insert in the threads increases the friction and reduces the likelihood of vibrations causing a change in the flow rate.

Plastic Needle Valves are an adjustable method of flow control. Internally, the pin and body create an adjustable orifice that restricts flow. Useful for instances when the exact flow rate hasn't been determined or to compensate for flow variation in other parts of the system. Very fine threads ensure adjustment accuracy. Thread interference increase the friction and reduce the likelihood of vibrations causing a change in the flow rate. All of the Air Logics products are assembled and tested in America. Plastic needle valves are tested for sealing and performance.
