Product Description
4WEH series solenoid pilot operated directional valves are solenoid pilot operated spool type valves. This series are used to control the start, stop and direction of flow. 4WH series hydraulic operated directional valves can be used to change the direction of hydraulic oil by moving the main spool when the valve receives a hydraulic signal from the pilot hydraulic oil.
