Part of GRACO's air controls and lubrication system for ram pumps, specifically engineered for President and Monark pump models Part of the air pressure regulation system for GRACO's Bulldog 43:1 air-powered pump designed for reliable operation with efficient, large ported air valve technology. Required in system to reduce risk of serious bodily injury, including fluid injection, splashing in the eyes, and injury from moving parts, if you are adjusting or repairing the pump. This valve relieves air trapped between the valve and the pump after the air supply is shut off. Trapped air may cause the pump to cycle unexpectedly. Locate the valve within easy access of the pump.
