Overview of directional seated valve type BVE 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 BVE is a screw-in valve. 2/2 and 3/2 directional seated valves are available. All connections can be subjected to the same pressures. Type BVE 1F according to D 7921 F can be used for highly viscous media...
