Direct Acting Differential Area Relief Valves - RD163T10V

Parker’s direct acting differential area relief valves are for fast response intermittent applications and work up to 380 bar (5500 psi) and 151 lpm (40 gpm). These valves have lower leakage rates and pressure rise than standard direct acting reliefs.
