This unit is a pilot operated, screw in cartridge style, sliding spool type, adjustable, internal pilot, hydraulic pressure breaker/sequence valve.
This is a normally open breaker/sequence valve, allowing flow from port 1 to port 2 and no flow from port 2 to port 3. When pressure in port 1 exceeds bias spring setting the spool will shift and stay shifted allowing no flow from port 1 to port 2 and pass flow from port 2 to port 3, until pressure at port 1 is removed. (Acts like a circuit breaker in a hydraulic system).
