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
Rexroth WEH10 Electro Hydraulic Operated Directional Control Valve Internal Supply & External Supply:
The M6 plug in P port of main valve is external pilot, as drawing "A"
To remove the M6 plug is internal pilot
Internal drain & external drain:
To remove the bolt, install M6 plug is external drain, as drawing "B"
To remove the M6 plug is internal drain
Pilot Oil Supply of 4WEH Type :
The pressure pilot oil is externally supplied via channel X, from separate pressure supply, the pressure pilot oil is externally drained via channel Y to the oil tank.
Pilot Oil Supply of 4WEH / E Type:
The pressure pilot oil is internally supplied from channel P of the main valve, the pressure pilot oil is externally drained via channel Y to the oil tank. The X oil port in the subplate is plugged.
Pilot Oil Supply of 4WEH / ET Type:
The pressure pilot oil is supplied internally from channel P of the main valve. The pressure pilot oil is drained internally via channel T to the oil tank. The X oil port and Y oil port in the subplate are plugged.
Pilot Oil Supply of 4WEH / T Type:
The pressure pilot oil is supplied externally via channel X from a separate pressure supply. The pressure pilot oil is drained internally through channel T to the oil tank. The Y oil port in the subplate is plugged.
