Technical Data

The directional control valves WL 4 /10 consist of housing(1), control spool (5), centering springs (4) and operatingsolenoids (2, 3).The three-position directional valves are fitted with twosolenoids and two springs. The two-position directionalvalves have one solenoid and one return spring.The operating solenoids are DC solenoids and are suppliedthrough connectors A, B (6, 7) without rectifiers. For ACsupply the solenoids are provided with rectifiers, which areintegrated directly into the connectors A, B (6, 7). Theconnectors do not belong to delivery and must be ordered

Functional Description

separately. By loosening the fixing nut (8), the solenoid canbe turned on its axis and fixed in three positions 90° apart.Provided that the pressure in T-port does not exceed363 psi (25 bar), the spool of the valve can be repositionedby manual override (9).The basic surface treatment of the valve housing (1) isphosphate coated, whereas the operating solenoids (2, 3)are zinc coated.
