Description

Load control valves of this type prevent a hydraulic actuator from running ahead of, or "over-running", the available oil supply. They simultaneously act as a load-holding-, safety- and pipe-rupture valve. Leak-free load control valves are especially suitable for high pressure applications up to 420 bar with a safety factor of 3.

Advantages

- the three functions: load control valve, safety valve and pipe-rupture protection are all integrated in one assembly
- load pressure acts in the closing direction; valve closes even with broken spring
- leak-free valve seats; heat-treated, ground and lapped
- more reliable operation over the whole pressure and flow range
- very good reproducibility
- special oscillation damping
- model with automatic overload compensation
- valve opening is independent of load pressure
