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

High-quality spherical poppet valves with guided, moving valve element 
"Made in Germany". 

Due to their special design, the valves can be used in many ways up
to an opening pressure of 2 bar and block the flow in the opposite direction 
up to a maximum operating pressure of 500 bar. 

Depending on the type of installation, three different categories and 
associated fitting tools are available:



  • Screw-in check valves

  • Press-in cartridge check valves
  • Plug-in check valves

  • Fitting tools

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
