Relief Valve – Direct Acting

Relief valves are passive components used to:

  • Act as safety valves. They protect fixed displacement pumps and directional control valves when pump output flow is intermittently blocked.
  • Limit pressure overshoot associated with pressure compensated pumps.
  • Protect hydraulic actuators (cylinders & motors) from shock pressures associated with starting and stopping heavy loads.

Specifications of Direct Acting (RD) Relief Valves:

  • Rated flow of up to 760 LPM
  • Maximum pressure of 420 Bar

Special features of Direct Acting relief valves(RD):

  • Direct Acting Relief valves (RD) boast Maximum leakage 7 cc per minute when operating at 90% of valves setting
  • Fast opening at 2ms.
  • Stainless Steel Direct Acting (RD) valves (External component) are also available.
