DESCRIPTION APPLICATION
Direct operated solenoid spool valve with 4 connections in 5 cham- These valves are suitable for applications in explosion-hazard
ber design. With the solenoids deenergised, the spool is held in the areas, open cast and also in mines.The stainless execution is espe-

center position by the spring (4/3), or switched back to the offset cially suitable for the use in wet and salty environment. Spool val-
position (4/2). With the impulse spool (4/2), the spool is held in the ves are mainly used for controlling direction of movement and stop-
switching position by the detent. The pressure tight encapsulated ping of hydraulic cylinders and motors.

Ex-protection solenoid coil prevents an explosion on the inside pe-
netrating to the outside as well as an ignitable surface tempera-

ture.
