VAL – Series 31

VAL-type valves prevent cylinders or motors from running ahead due to external loads. They shut off the port subjected to load pressure leak-free. Only when movement is to be initiated by the inlet pressure to the opposite side of the cylinder or motor does the valve open by this pressure acting as a pilot signal, and the load is lowered in a controlled manner. In addition to the load-holding and lowering function, the valves include a low-loss inlet check valve function and a pressure relief valve function. The opening point of the counterbalance valve depends on the set opening point of the pressure relief valve.
