PR-7000 Series Preset Precision Pressure Regulator
The Modular Precision Preset Regulator is designed to produce a precise output pressure that is preset. The regulator is ideal for instrumentation and industrial applications.
The standard preset model is factory preset to the desired output pressure, 0.5-40 PSI using 100 PSI supply. Specify the supply pressure if the supply is different than 100 PSI. The Preset Regulator is available with a recessed allen wrench adjustment or a removable adjustment knob.
The Unique Modular Dovetail design allows the regulator to be used individually or assembled into a modular combination of pneumatic components.

Solid Model Steps
- Download appropriate solid models and download the desired in and out ports
- Create new assembly
- Import the in port into the new assembly
- Import the outport(s) into assembly. Import once for each desired outport (ex. Import 3 times for 3 outports)
- Use mounting holes to constrain regulator ports
- Use bottom mounting surface to finish the constraint
- Repeat steps 3-5 for each additional port
- View the regulator from the top (knob is on the top of regulator)
- Review regulator selection guide and match the port selection to the model. Make sure to align the input port location.
- Save the assembly as the part number
- Optional: Combine model into a part
- Use solid model in customer assembly
Model Number Selection Guide
Order by model number and specify the preset output range 0.5 to 40 PSI using 100 PSI supply. Specify accessory letters or numbers for the dovetail ports and adjustment style. The regulator is supplied with an INPUT PORT, an OUTPUT PORT, and two BLANK PORTS as standard. Two accessory ports may be ordered. When choosing the port selection the INPUT PORT is the starting point. The remaining ports are then selected counterclockwise.
