4/3 Directional valve elements 8_58 EDZ-VEI) Functional description 3 Functional description 1 9 8 7 4 3 1 2 3 4 5 6 he sandwich plate design directional valve elements 8_58 are very compact direct operated solenoid valves which control the start, the direction and the leak free stop of the oil flow. hese elements asically consist of a stackale housing 1) with a control spool 2), one solenoid 5), a spring holder plug 7); two return springs 4); a solenoid screw-in cartridge VEI 8) with its coil 9). When energized, the force of the solenoid 5) pushes the control spool 2) from its rest position to the end position. If there is a solenoid cartridge VEI 8) type C,, O, the oil flow goes directly to the port ; if there is a solenoid cartridge VEI 8) type D Dual locking), it is necessary to energize the solenoid cartridge as well in order to allow the oil flow to the port. Once the solenoid 5) is de-energized, the return spring 4) pushes the spool thrust washer 3) ack against the housing and the spool 2) returns in its rest position. he leak free holding at port is provided y energizing or de-energizing, if the VEI is NC type) the solenoid cartridge. y energizing open the VEI 8) C and versions), the port is open to tank and downstream flow is possile. he coils are fastened to the respective solenoids 5) and VEI 8) y the ring nuts 6) and 1).
