Products Description
Type 4WE
Directional valves type WE are solenoid-operated directional spool valves and can be used as electromagnetic components. They
control the start, stop and direction of a flow.
The directional valves essentially consist of the housing (1), one or two electromagnets (2), the control spool (3) and the return
springs (4).
In the de-energized state, the control spool (3) is held in the middle or initial position by the return springs (4) (except
version “O”).
When the electromagnet (2) switching in oil is energized, the control spool (3) moves from its rest position to the desired end
position. This releases the required flow direction according to the selected symbol.
After switching off the electromagnet (2), the control spool (3) is pushed back to the middle or initial position (except for
valve with detent “OF” and valve without spring type “O”).
An auxiliary actuation (5) enables the valve to be switched manually without magnet supply.
The hydraulic system must be properly vented to ensure proper function.
Without spring return “O” (only possible with symbols A, C and D)
This version is a directional valve with two switching positions and two electromagnets without detent. The valve without spring
return on the control spool (3) has no defined basic position when de-energized.
Without spring return with detent “OF” (only possible for symbols A, C and D)
This version is a directional valve with two switching positions and two electromagnets with detent. The control spool (3) is
fixed in the respective switching position by the detents. During operation, the permanent current supply to the electromagnet can
thus be omitted, which contributes to energy-efficient operation.
Version “.73...A12” (soft switching behavior)
The composition of the control spools and solenoids greatly reduces the number of switching strokes that occur when the valves are
switched on or off. The switching strokes, measured as acceleration values a, can be reduced by approx. 85 % compared to the
standard valve, depending on the version of the control spool (see “Acceleration values”).
Notices:
Pressure peaks in the drain line to two or more valves may cause unintentional control spool movements in the version with detent.
It is recommended to lay separate return lines or to install a check valve in the drain line.
Due to the design principle, the valves are subject to internal leakage, which can increase during the service life.
