Electro Hydraulic Rexroth Valves with Directional Control



Directional spool valve type WEH electro-hydraulically operated
WEH32 electro-hydraulic directional control valve
Directional spool valves are used to conrol the start, stop and direction of fluid flow and thus the direction of movement or holding position ( cylinder or hydraulic motor ) is determind. The valves can be installed in hydraulic circuit in any position together with a subplate.
The connecting surfaces are sealed with O-rings that are included with the valve.

 
DESCRIPTION OF OPERATION



The directional valve is switched by changing position of the control spool 2 which moving along its axis separates or connects ports A, B, P or T in the housing 1.
Pressure supplied to one spring chamber 6 via the pilot valve 4 acts on the main spool surface and thus the main spool is shifted from its neutral position.
The main control spool is held in centre position by the spring 4 or hydraulically that is by fluid pressure affecting( via the pilot valve ) the both spool surfaces.
Centering sleeve 7 serves centering function.
The pilot valve is electrically operated by the solenoids 5, which may be equipped with the emergency button 8. The optional emergency button allows the operation of the pilot
valve without energisation subject to the pilot fluid pressure being at disposal.
The directional valve may be provided with the pilot choke adjustment 9.
