SJ-RVR PILOT OPERATED RELIEF VALVE, WITH REVERSE FLOW
DESCRIPTION
16 size, 1 5/16-12 thread, “SIXTEEN” series, pilot operated relief valve with reverse ow.
OPERATION
The SJ-RVR blocks ow from (2) to (1) until sufcient pressure is present at (2) to force the pilot stage off its seat,
allowing the main stage spool to shift, opening (2) to (1). The relief ow path is from (2) to (1). Reverse ow, from
(1) to (2), occurs when the pressure at (1) is at least 30 PSI (2.1 bar) higher then at port (2). The Cartridge offers
smooth transition in response to load changes in common hydraulic circuits.
FEATURES
• Hardened parts for long life.
• Industry common cavity.
