HE-RWP Rapid Response, Pilot Operated Relief Valve
DESCRIPTION
“High Pressure, High Flow, Rapid Response, 10 size, 7/8-14 thread, “Delta” series, pilot operated relief
valve.
OPERATION
The HE-RWP blocks flow from (2) to (1) until sufficient pressure is present at (2) to force the pilot stage
open, allowing the main stage to shift, opening (2) to (1).
FEATURES
• High pressure valve
• Hardened parts for long life.
• Industry common cavity.
• Rapid response to sudden pressure application
• Excellent regulation of pressure with flow (low override)
HYDRAULIC SYMBOL
This is a rapid response, high pressure relief valve with excellent
high flow regulation.
(Consult factory for higher flow capacity cavity option)
