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.
