Low Noise HRF-*04/06/10 (105.6 GPM Max.)

FEATURES

• HRF 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.
• Special internal passage design keeps flow noise to a minimum.
