The WEH25 E,F,J,H,G,U series of Rexroth WEH series electro solenoid hydraulic pilot operated directional valve adds an electro solenoid direction valve WE series as pilot
operated valve for controlling the X, Y oil port off and on by electro solenoids. The electro solenoid control hydraulic pilot operated directional valve has the advantage of large flow rate, reliable operation in high pressure, if compare with directional valve, there are two
valves combination because of pilot operated. The directional reaction is slower than normal directional valve, but it will accept the requirements of large flow and high pressure, and has the good anti pressure shock characteristics.
Rexroth WEH25 Electro Solenoid Hydraulic Pilot Operated Directional Valve
There are two voltages type of AC or DC solenoids option for electro solenoids, the flowing function is for different requirements option:
1. With or without the manual override,
2. The main valve with spring return, spring return with detent or without spring return,
3. With or without switching time adjustment valve Z2FS
4. With or without with the main valve stroke adjustment or the main spool end position indicator
5. Within the main valve can be installed preload valve.
6. Install the plug-in throttle
8. There are 19 standard operation spool for different working requirements.
WEH25 Electro Solenoid Control Hydraulic Pilot Operated Directional Valve Internal Supply & External Supply:
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.
