DESCRIPTION APPLICATION
Pilot operated 2/2-way solenoid poppet valve in screw-in cartridge These valves are suitable for applications in explosion-hazard
construction for cavity according to ISO 7789. The CB execution is areas, open cast and also in mines. Poppet valves are used where
closed in the energised position, the BC execution in the de-energi- tight closing functions of the valve are essential like leakage-free
sed position. In this, the main spool closes practically leakage-free load holding, clamping or gripping. For machining the cartridge
by means of the applied pressure. In the opposite flow direction, the cavity in steel and aluminum blocks, cavity tools are available (hire

valve opens after reaching the opening pressure. The pressure or purchase). Please refer to the data sheets in register 2.13.
tight encapsulated Ex-protection solenoid coil prevents an explo-
