DESCRIPTION APPLICATION
Direct operated solenoid spool valve with 4 connections in 5 These valves are suitable for applications in explosion-hazard
chamber design. With the solenoids deenergised, the spool is held areas, open cast and also in mines. Spool valves are mainly used
in the center position by the spring (4/3), or switched back to the for controlling direction of movement and stopping of hydraulic

offset position (4/2). With the impulse spool (4/2), the spool is held cylinders and motors.

in the switching position by the detent. The pressure tight
encapsulated Ex-protection solenoid coil prevents an explosion
on the inside penetrating to the outside as well as an ignitable

surface temperature.
