Direct Acting Differential Area Relief Valves - RDH103K10N

Name: Direct Acting Differential Area Relief Valves - RDH103K10N
SKU: RDH103K10N

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.
