DESCRIPTION APPLICATION
Direct operated 3/2-way solenoid poppet valve in flange construc- These valves are suitable for applications in explosion-hazard
DIMENSIONS tion. By means of the pressure tight switching solenoid, the poppet areas, open cast and also in mines. Poppet valves are used where
…22061 (solenoid on A side) …22060 (solenoid on B side) valve spool is opened or closed acting against the spring and is held tight closing functions of the valve are essential like leakage-free

in the switching position by the form-closed detent. Due to the load holding, clamping or gripping.

poppet spool construction with pressure compensation on both
9.5 sides, the flow through the valve is possible in both directions. The
5.5 metallically sealing seat closes the valve virtually leak free. The
8
pressure tight encapsulated Ex-protection solenoid coil prevents
an explosion on the inside penetrating to the outside as well as an
