Relief Valves: Pilot Operated (RP) & Direct Acting (RD)

Relief Valves: Pilot Operated (RP) & Direct Acting (RD)

Related Classifications: hydraulic valves, hydraulic pneumatic speed control check valves, hydraulic spool valve

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.


Original Press Release

Specifications of Pilot Operated (RP) & Direct Acting (RD) Relief Valves:

  • Rated flow of up to 760 LPM
  • Maximum pressure of 420 Bar
  • Special features of RP & RD relief valves:
  • Direct Acting Relief valves (RD) boast low leakage at less than 10 drops per minute when operating at 90% of valves setting as well as fast opening at 2ms.
  • Pilot Operated Relief valves (RP) are easily adjustable.
  • Stainless Steel Direct Acting (RD) valves (External component) are also available.
