SPECIFICATIONS SCHEMATIC
Solenoid Valve, Poppet Type, 2-Position, 3-Way, Pull-Type, 12-size.
When de-energized, the CP521-21 allows ow from port 1 to port
2, while port 3 is blocked. When energized, ow is allowed from
port 3 to port 1, while port 2 is blocked. Follow the “Operating
Envelope” limits to ensure shifting of the valve during operation.
This valve comes standard with a one-direction, push-pin manual
override.

These spool-type valves are commonly used in a selector circuit,
or as an on/o pilot control for a directional spool valve. 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. This valve can operate with an inlet pressure of
315 bar for 400,000 cycles. In case of inlet from port 2 this value
can be increased to 600,000 cycles.
* Rated Pressure based on NFPA fatigue test standards (at 1 Million Cycles).
