DESCRIPTION APPLICATION
Direct operated 2/2-, 3/2 and 3/4-way solenoid poppet valve in These valves are suitable for applications in explosion-hazard
sandwich construction. By means of the pressure tight switching areas, open cast and also in mines. Poppet valves are used where
solenoid, the poppet valve spool is opened or closed acting against tight closing functions of the valve are essential like leakage-free
the spring. Due to the poppet spool construction with pressure load holding, clamping or gripping. Miniature values are used
compensation on both sides, the flow through the valve is possible where both, reduced dimensions and weight are important.

in both directions. The metallically sealing seat closes the valve
virtually leak free.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.
