3 Function, section, symbols General: The cartridge solenoid valve is a direct operated pressure balanced /-way poppet valve. It controls the stop, start and direction of a flow. It basically comprises of a cartridge housing (6), the solenoid (7), the valve seat (3) and the closing element (5). Basic principle: The initial position of the valve is (normally open P or normally closed N ) determined by the closing element version (5) and the location of the spring (8). The /-way poppet valves are, due to their design, with regard to the adjustment force, always pressure balanced. Ports, can be applied with the maximum operating pressure of 350 bar and the flow can pass through in both directions (see symbols). With spool symbol P the closing element (5) is pressed onto the valve seat via the solenoid (7), and with spool symbol N the closing element (5) is pressed onto the seat via the spring (8). The flow is blocked leak-free. The hand override () permits the valve to be switched without energising the solenoid. Symbol "N": Version K: Version C: Version K0: Symbol "P": KSDER 3/6 RE /0.0

Effective filtration prevents faults from occuring and at the same time increases the component service life For the selection of filters see catalogue sheets RE ; RE , RE ) Further voltages on request. 3) Due to the occuring surface temperature of the solenoid coils, the European Standards EN563 and EN98 must be taken into account! When connecting the electrics, the protective conductor (PE ) must be connected according to the relevant regulations.
