Manifold Mount, Diaphragm Relief Valve

CAD Model


Description: Beswick’s RVD8 series miniature diaphragm relief valve is an excellent choice for applications requiring a valve which opens on rising pressure. The design offers compactness, light weight and high accuracy.  Performance is similar to the RVD series.

Features: Manifold mount configuration.

Max Supply Pressure Rating: 80 psig

Cracking Pressure Range: Recommended for cracking pressures in the 3-30 psig range. The large diaphragm sensing area and frictionless design, make it especially well suited for low cracking pressures, below 30 psig.  For applications requiring a cracking pressure up to 80 psig a higher pressure model is available upon request.  Please consult an Applications Engineer for additional details.

Approximate Weight: 25g in brass and stainless steel.  Weight will vary slightly, depending on configuration. Selecting the 2 inch. high resolution cap option adds approximately 50-60g to total weight.

Porting: 10-32 external threaded outlet port.  0.050″ (1.27mm) diameter inlet ports. 


  • Adjustable relief pressure setting.
  • Manifold mount configuration.
Note: Care must be taken during installation to avoid shearing the manifold mount thread.  Recommended torque spec is 7-9 in lbs.
