Regulators For Pressure Control

July 26, 2011

Swagelok® RHPS series general industrial regulators offer accurate pressure control of pressures from 0 to 5800 psig (0 to 400 bar) in gas and liquid systems, ½ to 2-inch sizes. RS and RSH model regulators employ either a spring-loaded diaphragm or piston as the sensing element, depending on the outlet pressure range desired. The RS model is available with a choice of six outlet ranges; from 0 to 43 psig (0 to 3 bar) up to 0 to 5075 psig (0 to 350 bar). The RSH model is available with a choice of nine outlet ranges; from 0 to 43 psig (0 to 3 bar) up to 0 to 10,150 psig (0 to 700 bar). The LPRS model regulator, with larger diaphragm, offers tight control of low pressures spanning 1.5 to 43 psig (0.1 to 3 bar), making it ideal for applications requiring a second regulator for two-stage reduction of pressure. Temperature range for all models is -4 to 176 F (-20 to 80 C).
