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
