PILOT OPERATED RELIEF VALVE
RF SERIES
FEATURES
• RF series relief valve is
designed on the theory of differential pressure created by flow
across the orifice of the balance piston. This differential
pressure acts to open the piston against the spring, permitting
enough fluid vented to tank at the set pressure.
• Piston moves smoothly, and controlled by pilot pressure,
provides stable pressure control and good repeatability.
