Swagelok's RHPS series PRV model proportional relief valves provide proportional venting of overpressures
Swagelok RHPS series PRV model proportional relief valves are designed to provide proportional venting of overpressures for piping systems up to 1 inch. End connections include NPT female, BSPP female and BSPP male in 1/4-, 1/2-, 3/4- and 1-inch sizes. Available Swagelok threaded adapters convert from BSPP to NPT.
The PRV’s balanced valve design is engineered to be unaffected by system back pressure up to 50% of the valve’s set pressure. PRV proportional relief valves feature 316L stainless steel construction of the body, trim and spring housing. Choose fluorocarbon or nitrile seats and seals.
Available set pressure ranges are: 145 to 580 psig (10 to 40 bar), 580 to 1160 psig (40 to 80 bar), 1160 to 2170 psig (80 to 150 bar), 2170 to 4060 psig (150 to 280 bar) and 4060 to 5800 psig (280 to 400 bar). Depending on body size selected, flow coefficients (Cv) range from 0.49 to 4.36. Operating temperature range is -4 to 176° F (-20 to 80° C).
