The Graco 16E845 Outlet Valve regulates paint flow and maintains consistent fluid pressure to ensure a uniform finish during high-pressure airless spraying applications. This precision-engineered fluid management component serves as the primary discharge control valve within the sprayer's pump block. It works by utilizing a responsive, spring-loaded ball and seat mechanism that opens instantly to release pressurized coating material into the hose during the pump cycle, and seals tightly to prevent fluid backflow on the return stroke. This continuous regulation keeps the spraying system primed and eliminates pressure drops. Keep your tools organized and ready with a reliable toolbox and the Graco pressure washer outlet valve​ for your next project. #Graco #16E845 #OutletValve #PowerToolsParts #powertools #HomeImprovement
