WH Pilot operated, directional spool valve operates like a normal directional valve that is used to open and closed hydraulic flow and switch flow direction. The Directional spool valve WH series we produced is mostly used where a large flow rate of more than 100L/min is required.
WH Pilot operated, directional spool valve produced is most used in the plastic modeling machines which requires the large flow rate. The WH series of 10 size valves is often used in high flow hydraulic unit sand hydraulic systems, it usually equipped with 4WE6E, 4WE6H, 4WE6J as a pilot operated control.
