FUNCTIONAL DESCRIPTIONThe directional control valve WE 10 AH essentially consists ofthe valve housing (1), the control piston (5) with twoCentering springs (4) and - depending on the application - one or twoElectromagnets (2 + 3) as actuators.Directional control valves with three switch positions have twoElectromagnets and two centering springs. Directional control valves withtwo switch positions are either with oneElectromagnet and a return spring or twoElectromagnets and a locking device.The control piston is activated by the electromagnets (2 + 3)(5) from its rest position to the desired end positionpushed. It gives the connection PComing pressure oil to port A or B free. AtInterruption of actuation will cause the spool inrested his rest position, or by resting in theheld respective end position.The electromagnets work with DC voltage. For theAC power supply are either inthe plug bases of the solenoid coil or in theDevice sockets (6 + 7) integrated rectifiers used.The device sockets can each be rotated 90 °.By loosening the fastening nut (8) you canturn the electromagnets (2 + 3) by 360 ° orswitch. The pressure-tight anchor tube is screwed in.This allows the solenoids to be opened without opening thepressure-tight room can be changed.In the event of a malfunction or a power failure, theControl piston by hand using the emergency manual operation (9)be adjusted.The surface of the valve body is phosphated andthe actuating magnets are galvanized
