Wandfluh Hydraulic Check Valves

There are several type of check valves available from Wandfluh, as follows:

  • Non-return valves allow flow in one direction and prevent flow in the other direction, closing off the possibility of backflow of pressurized hydraulic fluid.
  • Drain valves are mainly used in systems with an accumulator requiring pressure reduction.
  • Pilot-operated non-return valves are used to shut off pressurized hydraulic cylinders without leaking.
  • Pipe failure valves protect against uncontrolled pressure drops after a hydraulic line rupture.
