This is a solenoid valve, spool-type, 4-way, 2-position, 12-size.
When de-engergized, the CP531-21 allows ow from port 3 to port
4, and from port 2 to port 1. When energized, ow 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 ow 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.
* Rated Pressure based on NFPA fatigue test standards (at 1 Million Cycles).
