Excavator Pipe-Rupture Valve RS



Pipe-rupture valves are used wherever a load must not be allowed to drop rapidly and without control if a pipe or hose bursts (ex. uncontrolled movement of the cylinder). In its normal position the pipe-rupture valve is open and allows the flow in both directions. When the actuating flow rate is exceeded – by a hose burst, for example – the pipe-rupture valve closes suddenly and blocks flow without leakage.


Due to their very high closing speed, these products are not suitable for applications that include the transportation of people. The activation of the pipe-rupture valve produces very large deceleration's that can have adverse health effects.


  •    -  Leak-free closure
  •    -  Closing flow rate is adjustable
  •    -  Compact design means small space requirements
  •    -  Available as a cartridge or in a block body
