EDBZ-VEI

Valve elements with 4 ways and 2 positions.

Control spools directly operated by solenoids with removable coils.

In the de-energized condition, the control spool is held in the central position by return spring.

Wet pin tubes for DC coils, with push rod for mechanical override; burnish surface treatment.

Manual override (push-button or screw type) available as option.

Additional solenoid cartridge 2/2, NO or NC, single locking or dual locking on port A.

Size 4

Series 00

Maximum operating pressure 310 bar (4500 psi)

Maximum flow 25 l/min (6.6 gpm)

Port connections G 3/8 SAE6 - M16×1.5

1) For connectors ordering code see data sheet RE 18325-90.

2) VEI solenoid cartridge must be ordered separately.

The sandwich plate design directional valve elements B8_58… are very compact direct operated solenoid valves which control the start, the direction and the leak free stop of the oil flow. These elements basically consist of a stackable 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 “0” to the end position “b”. If there is a solenoid cartridge VEI (8) type C, A, O, the oil flow goes directly to the port A; 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 A. Once the solenoid (5) is de-energized, the return spring (4) pushes the spool thrust washer (3) back against the housing and the spool (2) returns in its rest position. The leak free holding at port A is provided by energizing (or de-energizing, if the VEI is NC type) the solenoid cartridge. By energizing open the VEI (8) (“C“ and “A“ versions), the A port is open to tank and downstream flow is possible. The coils are fastened to the respective solenoids (5) and VEI (8) by the ring nuts (6) and (10).
