  • Flows to 30 U.S. gpm at pressures to 15 000 psi (114 L/min at 1040 bar).
  • Relief valves regulate pressure and protect circuits.
  • Unloading valves divert pump output to tank in response to a pilot pressure signal.
  • Decompression valves reduce flow surges for less vibration and noise.
  • Suitable for use with some water-based, fire-resistant and other special fluids including water glycol, various military fluids, Skydrol and other phosphate ester fluids.
  • Line connected or subplate mounted.
  • Optional integral vent valve for remote pressure control.

  • Relief, reducing, unloading, counterbalance and sequence functions available
  • Rated to 90 US gpm at 5000 psi (341 L/min at 350 bar).
  • Some models available with integral reverse free-flow check valves.
  • Optional integral vent valve for remote pressure control.
  
  • Poppet style valves for fast response to regulate pressure.
