Normally open cartridge valves require an external pilot signal to close the valve against system pressure. This valve range is ideally suited for applications requiring a prefill valve or decompression valve. The main spool consists of a sleeve with a sharp edged seat and a piston. A spring holds the piston in the open position. Pressure at control port X forces the poppet against the spring to close the valve.
