Operation

This is a normally-closed, pilot-operated, poppet-type 20-size solenoid valve with free reverse flow.  When de-energized, the valve acts as a check valve, allowing flow from port 1 to port 2, and blocking flow from port 2 to port 1.  When energized, the valve’s poppet is shifted and allows flow from port 2 to port 1, and from 2 to 1.

Applications

This valve is designed for low leakage applications and can be used in a circuit with a single acting cylinder to control motion, provide load holding or as a general purpose diverter or dump valve.  This solenoid valve is a technical replacement for CP503-3.
