The WEH10 E,F,J,H,G,U series of Rexroth WEH10 electro hydraulic operated directional control valve is a solenoid valve and hydraulic control valve combination, which is controlled by
hydraulic control valve solenoid valve action, transform the direction of fluid flow control
valves.
Rexroth WEH10 Electro Hydraulic Operated Directional Control Valve
The Rexroth WEH10 electro hydraulic operated directional control valve is mainly used in the flow over the range of the WE
solenoid valve in the high flow hydraulic system, the electro control and hydraulic operated of the action control device, or to control the oil flow direction.
1. Electro hydraulic operated directional control valve can be installation in standard subplate mounting, giving priority to horizontal position.
2.
Hydraulic system used in the medium must be filtered, filtering accuracy of at least 20μm.
3. High strength screw of 10.9 degree must used
4. And the valve connecting the surface roughness Ra0.8, flatness requirements 0.01/100mm
