LOWERING VALVES TYP VAL - series 79
Description
Valves of type VAL prevent moving ahead of cylinders or motors due to external loads. They lock the connection to which the load pressure acts leakage free. Only when a movement is to be initiated by the inlet pressure on the opposite side of the cylinder or the motor, the valve is opened by this pressure acting as a pilot control signal and the load is lowered in a controlled manner. In addition to the load holding and lowering function, the valves includes a low-loss check valve function and a pressure-limiting function.
Characteristics
- leakage free holding function
- controlled lowering of the load
- minimum flow losses
