Hydraulically pilot-operated check valves

Hydraulisch entsperrbare Rückschlagventile

  • Excellent closeness
  • For high dynamic loads
  • Hydraulic cushion
  • Long life
  • Easy to assemble

Hydraulically pilot-operated check valves (cartridge design) enable a quick 
fluid flow with low pressure drop as well as a reliable seal-tightness after 
the throughflow. With a hydrauliic controlled unlocking piston the shut off
pressure can be reduced quickly.

The valves can be delivered with or without pressure drop (by request). 
There are different opening pressures up to 2 bar possible. The maximum 
working pressure is 200 bar. The screw in valves are available in different sizes.

Key Benefits

  • Excellent closeness
  • Low pressure drop
  • Flow rate up to 30 l/min 
(hydraulically pilot-operated check valves E)
and 80 l/min (cartridge check valves R)
  • For high dynamic loads
  • Reduced turbulent flow
  • Hydraulic cushion
  • Long life
  • Easy to assemble
