Beswick Engineering Co., Inc. Two-Stage Manifold Mount Regulator PRD28

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. Wetted Materials: 302, 303 and 316 Stainless Steel internals. Brass body. Outlet Pressure Range: Maximum outlet range 0-30 psi. 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 0.5 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. Selecting the 2 inch. high resolution cap option adds approximately 50-60g to total weight. This is a Non-Relieving regulator. Porting: 5/16-24 external threaded inlet port & 3/32†(2.4mm) diameter outlet port. Recommended Porting Dimensions Flow Curves
