KRACHT - Model NG 10 WL 4.10 -Directional Control Valves

The directional control valves WL4/10 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 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.
