GRACO 563057 - Single Ball Check Valve 35 Nominal Cracking Pressure, 1/4-19 in BSPP, Steel, 5000 PSI
Single Ball Steel Check Valve designed for use in hydraulic or lubrication systems with pressures up to 5000 PSI. Features positive seal that prevents leakage and backflow in a compact, easy-to-install design. Uses standard ball and spring principle with incoming flow pushing ball from valve seat to permit lubricant flow, and spring expansion re-seating ball when flow stops to create positive seal.
