CP531-21 Solenoid Valve
English Chinese (Simplified)

comatrol hydraulic cartridge valves



This is a solenoid valve, spool-type, 4-way, 2-position, 12-size. When de-engergized, the CP531-21 allows flow from port 3 to port 4, and from port 2 to port 1. When energized, flow s allowed from port 3 to port 2, and from port 4 to port 1. Follow the ‘Operating Envelope’ limits to ensure shifting of the valve during operation.





These valves are primarily used in mobile and industrial applications for controlling the direction of the flow in a circuit, like motors or cylinders. Solenoid spool-type valves are direct acting and respond quickly to coil voltage input.  Spool valves will have some leakage due to spool clearance, so if your application requires no leakage at the working port(s), apply a low leakage poppet valve(s), like PO check valve, counterbalance valve, etc., in addition to this solenoid valve.
