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
flange construction. By means of the pressure tight switching sole- areas, open cast and also in mines. Poppet valves are used where
noid, the poppet valve spool is opened or closed acting against the tight closing functions of the valve are essential like leakage-free

spring. Due to the poppet spool construction with pressure load holding, clamping or gripping.

compensation on both sides, the flow through the valve is possible
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.
