Hydropa WE6AHY-E2A/W Directional Control Valve

FUNCTIONAL DESCRIPTION

The directional control valve WE 6 AH essentially consists of

the valve housing (1), the control piston (5) with two

Centering springs (4) and - depending on the application - one or two

Electromagnets (2 + 3) as actuators.

Directional control valves with three switch positions have two

Electromagnets and two centering springs. Directional control valves with

two switch positions are either with one

Electromagnet and a return spring or two

Electromagnets and a locking device.

The control piston is activated by the electromagnets (2 + 3)

(5) from its rest position to the desired end position

pushed. It gives the connection P

Coming pressure oil to port A or B free. At

Interruption of actuation will cause the spool in

rested his rest position, or by resting in the

held respective end position.

The electromagnets work with DC voltage. For the

AC power supply are either in

the plug bases of the solenoid coil or in the

Device sockets (6 + 7) integrated rectifiers used.

The device sockets can each be rotated 90 °.

By loosening the fastening nut (8) you can

turn the electromagnets (2 + 3) by 360 ° or

switch. The pressure-tight anchor tube is screwed in.

This allows the solenoids to be opened without opening the

pressure-tight room can be changed.

In the event of a malfunction or power failure, the

Control piston by hand using the emergency manual operation (9)

be adjusted.

The surface of the valve body is phosphated and

the actuating magnets are galvanized.
