4/3, 4/2 and 3/2 Directional Valve with Wet-pin AC or DC Solenoid
Type WE 10...L3X
Features:
– Direct operated directional solenoid valve, standard version
– Porting pattern according to DIN 24 340 form A,ISO 4401 and CETOP-RP 121 H
– Wet pin DC or AC solenoids with detachable coil
– Pressure-tight chamber needs not to be opened for a coil change
Function and configuration
Type WE valves are solenoid operated directional spool valves. They control the start, stop and direction of flow.
The directional control valves consist of housing (1), one or two solenoids (2), the control spool (3), and one or two return springs (4).
In the de-energized condition the control spool (3) is held in the neutral or initial position by means of return springs (4) (except for pulse spools). The control spool (3) is actuated via wet pin solenoids (2).
To ensure proper operation, care must be taken that the pressure chamber of the solenoid is filled with oil.
The control spool(3) is moved to the expected position by solenoid(2) and pushing rod(5), and this gives free-flow from P to A and B to T or P to B and A to T.
When solenoid (2) is de-energized, the control spool (3) is returned to its neutral position by means of the return springs (4).
The solenoids may also control the control spool (3) by an optional override button (6) under the de-energized condition.
For application in voltage pulsation, solenoids with large scope voltage are recommended.
For application in high protective grade, waterproof plug should be used.
Type 4WE10.. L3X/O... (Only for symbols A, C and D)
This Type is a 2-position directional valve with 2 solenoids without detents. The spool position, when the solenoids are de-energised, is not defined..
Type 4WE10.. L3X/OF... (Impulse spool, only for symbols A, C and D)
This Type is a 2-position directional valve with 2 solenoids and detents. Hence, when the solenoids are de-energized, the spool is held in the detented position then the solenoids do not need to be continuously energised.
Throttle insert (type 4WE10...L3X/.../B..)
The use of a throttle insert is required if, due to the operating conditions, flows can occur during the switching process which are larger than the performance limits of the valve allow.
The orifice is to be inserted into the P channel of the directional valve.
