91 54 10 HYDRAULIC CONNECTION Direct operated 2/2-, 3/2 and 3/4-way solenoid poppet valve in These valves are suitable for applications in explosion-hazard
146 B..22041a flange construction. By means of the pressure tight switching sole- areas, open cast and also in mines. Poppet valves are used where
156 B..32041a 28 noid, the poppet valve spool is opened or closed acting against the tight closing functions of the valve are essential like leakage-free

E = Air bleed screw 14 spring. Due to the poppet spool construction with pressure load holding, clamping or gripping.
Dimensions of the solenoid coil see data sheet 1.1-183 and 1.1-184 compensation on both sides, the flow through the valve is possible
The distance plate BDP4/12 has to be ordered separately P in both directions. The metallically sealing seat closes the valve
3/4-way A B virtually leak free. The pressure tight encapsulated Ex-protection
14 27 solenoid coil prevents an explosion on the inside penetrating to the

T T0 outside as well as an ignitable surface temperature.
