	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) When cutting off electricity 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 obtaining satisfied with operation, the pressure cavity of solenoid must be filled with oil. The force of solenoid(2) going through rod (5) is acting on control spool (3) it will push on required position while on static position. The oil freely flows from P to A, B, to T P to B or A to T When the solenoid (2) off the control spool(3) will be pushed on original position by reset spring(4) For selection of manual urgent operation (6) can control the spool (3) motion when the solenoid is off  4WE 6..6X/O…type (only limiting symbol A.C.D)  The type consists of two switching positions and two solenoids without positions directional control valve 4WE 6..6X/OF…(pulse valve, only limiting symbol A.C.D) It consists of two switching position two solenoide and one positioner directional control valve Two switching positions are respectively fixed so the solenoid needn't requiring for long time woking  Insert throttling valve (4WE 6..6X/…/B..) Because of especial working state when switching it may appear as exceeding function curve of allowance flow under this condition it needs to mount insert thnttling plug The plug is mounted on P port of directional control valve.

	Characteristic curve (be measured when ν=41mm2 /s t=50°C)
	7 symbol “R”is on switching position A-B 8 symbol “G”and “T”is on center position P-T
	Switching function limit (be measured when ν=41mm2 /s t=50°C)
	Working limit for giving is useful for two direction flowing condition (as for P port flow to A of returning of B to T at the same time ) When single direction flow (if the port from P to A B is plugged )because of flow strenth in the valve allowance switching limit may fall cloun Working limit is measured when solenoid is on working temperature owing volt 10% and the reservoir without bearing pressure
