Miniature Manifold Mount Diaphragm Relief Valve

Featured Product from Beswick Engineering Co., Inc.

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.

Cracking Pressure Range:  The large diaphragm sensing area and frictionless design, make it especially well suited for low cracking pressures, below 30 psig.

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.
