4WE6 Solenoid Directional Valve: Spool Type Guide
Not every hydraulic circuit is controlled by hand.
Manual valves work well when an operator stands at the machine. But once a PLC, timer or remote signal takes over, a lever is no longer enough. That shift brings a selection question with it: when the solenoid is de-energized, what should the actuator do?
The problem: neutral position behaviour is often decided late
Many circuit designs specify the valve model and voltage early, but leave the spool type until the end. The spool type decides the flow path in the neutral position. Some circuits need the actuator to hold position. Some need it to return. Some need the pump to unload. Get this wrong, and the machine behaves differently from the schematic every time power is cut.
The solution
The 4WE6 Solenoid Directional Valve for Automated Hydraulic Circuits from Onederful shifts the spool by electrical signal, with multiple spool types available.

Key specifications:
Max working pressure P/A/B: 35 MPa
Max working pressure T: 21 MPa
Max flow: 80 L/min
Working voltage: DC 12V / 24V, AC 110V / 220V
Two details are worth confirming before ordering. Voltage must match the system's control power supply. The T port must be connected to tank, otherwise the spool cannot shift properly.
Where it fits
The 4WE6 suits circuits commanded by a PLC output, a manual switch, or a timer and sequence controller. It is common in automated production equipment.
