HT-RVP Pilot Operated Relief Valve
DESCRIPTION
12 size, 1 1/16-12 thread, “Tecnord” series, pilot operated relief valve.
OPERATION
The HT-RVP blocks flow from (2) to (1) until sufficient 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 cartridge offers smooth transition in response to load changes in common hydraulic circuits.
FEATURES
• Hardened parts for long life.
• Industry common cavity.
Undercut cavity recommended for circuits above
2500 PSI where flows go to 30 GPM.
