GRACO 563055 - Single Ball Check Valves - 35 PSI Nominal Cracking PSI, 9/16-18" SAE (M x F), SS body/steel ball, 3, 500 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 with 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.
