DESCRIPTION APPLICATION
Direct operated 2/2-way solenoid poppet valve in sandwich Poppet valves are used where tight closing functions of the valve
construction. By means of the pressure tight switching solenoid, are essential like leakage-free load holding, clamping or gripping.
the poppet valve spool is opened or closed acting against the Miniature values are used where both, reduced dimensions and
