M3 Port, Two-Stage Diaphragm Regulator

CAD Model


Note: The PRD2 will be discontinued soon and is not recommended for new designs. It has been replaced by our PRD3 two stage regulator which you can find here.

Description: The PRD2 is a miniature, dual stage, diaphragm style, pressure regulator.

Max Inlet Pressure Rating: This is a two stage regulator, and is ideal for applications with fluctuating or decaying inlet pressures, up to a maximum of 500 psig.



Outlet Pressure Range: Maximum outlet range 0-20 psig. The large valve to sensing area ratio and frictionless design of Beswick’s diaphragm style regulators make them especially well suited for low pressure regulation, such as ½ psi. The two stage design allows the regulator to maintain a consistent outlet pressure despite wide swings in the inlet/source pressure.


Approximate Weight: 50g in brass and stainless steel (303 & 316), 23g in aluminum. Weight will vary slightly, depending on configuration. Selecting the 2 inch. high resolution cap option adds approximately 50-60g to total weight.


Porting: M3x0.5 internal threaded inlet and outlet ports.

This is a Non-Relieving regulator.
