R-7000 Series Precision Pressure Regulator

The Modular Subminiature Precision Pressure Regulator is designed for precise regulation of pressure. It is ideal for instrumentation and industrial applications. The pressure regulator has a 20 turn adjustment range from 0.5 to 100 PSI. Maximum supply is 150 PSI. Four adjustment ranges are available: 10 PSI, 30 PSI, 60 PSI and 100 PSI. The standard device is furnished with an adjustment knob and is also available with an extended 1/4" shaft to accept an adjustment knob or furnished with an exposed screwdriver adjustment by which the pressure range can be adjusted.

The Unique Modular Dovetail design allows the regulator to be used individually or assembled into a modular combination of pneumatic components.

Solid Model Steps

  1. Download appropriate solid models and download the desired in and out ports
  2. Create new assembly
  3. Import the in port into the new assembly
  4. Import the outport(s) into assembly. Import once for each desired outport (ex. Import 3 times for 3 outports)
  5. Use mounting holes to constrain regulator ports
  6. Use bottom mounting surface to finish the constraint
  7. Repeat steps 3-5 for each additional port
  8. View the regulator from the top (knob is on the top of regulator)
  9. Review regulator selection guide and match the port selection to the model. Make sure to align the input port location.
  10. Save the assembly as the part number
  11. Optional: Combine model into a part
  12. Use solid model in customer assembly
