11197803 - DIRECTIONAL CONTROL VALVE PSV08-34-05-00-00-12-B-00 - Danfoss

This is a 4-way, 3-position, spool type, non-compensated proportional directional valve. In its de-energized condition, port 3 is blocked, while ports 2 and 4 are open to port 1. Increasing the current to the bottom coil will cause the spool to move, proportionally opening flow from port 3 to 2 with return flow passing from port 4 to 1. Increasing the current to the top coil will proportionally open flow from port 3 to 4 with return flow passing from port 2 to 1. Using this as a variable orifice in conjunction with a compensator, the valve will provide compensated flow to an actuator in both directions. Port 1 should be used as the tank port with a maximum back pressure of 150 bar. For applications with unequal flows, the highest flow should be connected to Port 2.
