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 closed breaker/sequence valve, blocking flow from port 2 to port 3. Port 1 is as external pilot port. when pressure in port 1 exceeds spring bias setting, the spool will shift and stay shifted allowing flow from port 2 to port 3, until pressure at port 1 is removed. (Acts like a circuit breaker in a hydraulic system).
