Overview of directional seated valve type VP Directional seated valves are a type of directional valve. Their function is to direct the ow of hydraulic medium in certain directions, therefore connecting the relevant connections, or shutting off the ow with zero leakage. By this means they control the movement of the actuators in a hydraulic system. The directional seated valve type VP is a manifold mounting valve. It is a coneseated valve. 2/2, 3/2 and 4/2 directional seated valves with different types of actuation are available. All connections can be subjected to the same pressures. The directional...
