Overview of directional seated valve type NBVP 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 type NBVP is a manifold mounting valve with standard connection pattern nominal size NG 6. 2/2-, 3/2-, 3/3-, 4/2-, 4/3- and 4/4-way directional seated valves with different types of actuation are available. All listed types are coneseated valves...
