Miniature two-stage diaphragm pressure regulator
0 - 5 psi | PRD28-.N1 Beswick Engineering Co, Inc.

Description: The PRD28 series regulator is a two stage manifold mount regulator. The first stage is a piston stage, and the second a diaphragm stage.

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: 52g in brass. Weight will vary slightly, depending on configuration.


Porting: 5/16-24 external threaded inlet port & 3/32” (2.4mm) diameter outlet port.
This is a Non-Relieving regulator.
