Principle of operation

|
|
|
|
|
WE type directional control valve is operated by the solenoid to control flow direction and on-off the valve is mainly comprised of valve body (1) one or two solenoids (2) control spool (3) and one or two reset
springs(4)
Under static condition the control spool (3) is on center or original position by reset spring (4) cexcept for pulse valve The control spool(3) is operated by wet
solenoid(2)
To ensure for right function the solenoid armature sleeve must be filled with
oil
The force of solenoid(2) is acting on control spool (3) it will push on required position while on static position. The oil allowably flows from P to A and B, to T or P to B and A to T When the solenoid (2) is off the control spool(3) will be pushed on original position by reset spring(4) Elective urgent operation (5) can control the spool (3) motion when the solenoid is off the spool position is not certain.

WE10.3X/OC…type (only spool A. C and D possibility)
This type is double solenoid for two position directional valve it has not positioner and reset spring When the solenoid is off the spool position is not
certain
WE10.3X/OFC…type (pulse operation) with positioner (only spool A. C and D
possibility) This type is double solenoid for two position directional valve it has positioner but not reset spring When the solenoid is off the spool position is fixed Therefore it
needn't to supply electricity for the solenoid continyously.
Insert throttling plug (WE10…3X/…/B..type)When operating the valve if producing large flowrate that exceeds power limit of the valve which is allowable it needs an insert throttling plug.The plug is mounted on P port of the valve

Function limit (be measured when ν=41mm2 /s
t=50℃)
|
|
|
Function limit for giving is useful for valve bearing two directions flow at the same time (such as from P to A, B to T at the same time)
Because of producing flow strenth in the va;ve allowance function limit may be reduced more for single direction flow (such as from P to A, B port is
plugged)
This working limit is measured when solenoid is on working temperature owing volt 10% and no return pressure
