Adjustable pressure refief valves

Druckbegrenzungsventil

Adjustable pressure relief valves protect your system from exceeding the 
maximum allowed pressure. They open when the maximum allowed pressure 
is achieved and reduce the system pressure optionally abrupt or throttled 
down.



The screw-in hydraulic valves (cartridge design) are available in different
adjust versions from 5 – 300 bar (standard adjust range +/- 50 bar) and with
metric or whitworth thread. Stainless steel valves can also be offered for 
other mediums or for high temperature usage.

Key Benefits

  • Excellent closeness
  • Compact design
  • For high dynamic loads
  • Long life
  • Easy to assemble

Fixed pressure relief valves offer further advantages:

  • User-defines opening pressures up to 350 bar
  • Reduced turbulent flow
  • Insensitive to dynamical acceleration

Adjustable pressure relief valves offer further advantages:

  • Low pressure drop
  • Any opening pressures
  • Hydraulic cushion
