Technical Data
The directional control valves WL 4/10 consist of housing
(1), control spool (5), centering springs (4) and operating
solenoids (2, 3).
The three-position directional valves are fitted with two
solenoids and two springs. The two-position directional
valves have one solenoid and one return spring.
The operating solenoids are DC solenoids and are supplied
through connectors A, B (6, 7) without rectifiers. For AC
supply the solenoids are provided with rectifiers, which are
integrated directly into the connectors A, B (6, 7). The
connectors do not belong to delivery and must be ordered
Functional Description
separately. By loosening the fixing nut (8), the solenoid can
be turned on its axis and fixed in three positions 90° apart.
Provided that the pressure in T-port does not exceed
363 psi (25 bar), the spool of the valve can be repositioned
by manual override (9).
The basic surface treatment of the valve housing (1) is
phosphate coated, whereas the operating solenoids (2, 3)
are zinc coated.
