4/3 Directional Control Valve – 4WEH I 10 / 4WEH EI 10
The 4WEH I 10 and 4WEH EI 10 valves are 4/3 directional control valve, electro-hydraulically operated.
HYDAC 4/2 and 4/3 directional valves for oil hydraulic systems are to open and close flow paths. In de-energized mode the main piston will be retained by a spring in the initial position. An under oil switching magnet pushes the pilot piston in its end position whereby the main piston – hydraulically operated – moves to his end position.
Hereby the chosen flow paths will be enabled according to the symbol of the valve. After switching off the solenoid the pilot piston will be pushed back in its initial position by the spring. A manual override allow the switching of the pilot valve without erection of the solenoid.
- Electro-hydraulically operated by pilot valve NW6
- Flows up to 150l/min
- Internal or external pilot supply and drain line selectable by internal plug setting
