Beswick Engineering Co., Inc. Two-Stage High Pressure Piston Regulator PR3HP

Beswick’s PR3HP is a compact , piston based, two stage regulator, ideal for applications requiring accurate regulation of high-pressure fluids down to lower pressures. NOTE: Please review the Low Flow Oscillation Graph below for data on recommended flow range. The PR3HP expands upon the capabilities of our PR series piston-based regulators, by adding an additional stage to allow higher inlet pressures. Our piston style regulators utilize coil springs, and are well suited for applications requiring higher outlet pressures (minimum 10 psi). The first stage valve seat is made from PEEK for improved high temperature performance. Max Inlet Pressure Rating: The PR3HP is a two-stage regulator, capable of accurately reducing inlet pressures of up to 3,000 psi. It is well suited for applications where the source fluid is supplied by high pressure gas cylinders. Outlet Pressure Ranges: The PR3HP has available outlet ranges of 0-50 psig, 0-100 psig and 0-400 psig. The two-stage design allows the regulator to maintain a consistent outlet pressure despite wide swings/decays in inlet pressure. Material: 303 Stainless Steel Body Approximate Weight: 76g in 303 stainless steel. Weight will vary slightly, depending on configuration. Porting: ¼-28 internal threaded inlet port, 10-32 internal threaded outlet port. This regulator is available in both Relieving and Non-Relieving types. Mounting: Most models are supplied with a 15/32-32 thread, with two 9/16″ hex nuts and 2 washers for panel mounting. Flow Curves Low Flow Oscillation Range
