GRACO 237540 - Low Pressure Ball Valve Compatible w/ stainless steel, Catalyst & Waterborne Materials, 1/2" OD Tube x 3/8" NPSM(m), 500 PSI
Low pressure ball valve designed for finishing applications, featuring stainless steel and PTFE construction for compatibility with catalyst, waterborne, and other finishing materials. Engineered with multiple connection options to meet specific application needs.
Features:
Use for on/off fluid control. Allows safer system operation by permitting relief of fluid pressure or isolation of components from pressure during maintenance. Ball vales must be used in the fully open or closed position. Do not throttle the valve - it could cause premature seal failure.
