Integrated check valve acting as an anti-cavitation valve

When installed close to actuator the valve can be used as a hose burst valve

Back pressure has got negligible effect on relief setting nor the required pilot pressure

Setting can be performed during machine operation = leak free closing of adjustable element

Wide range of relief pressure setting up to 420 bar (6100 PSI)

In the standard version, the valve is zinc-coated for 520 h protection acc. to ISO 9227
