GRACO 237528 – Low Pressure Ball Valve, 1/4 NPT(M) x 1/4 NPT(M), Stainless Steel, Catalyst &

GRACO 237528 – Low Pressure Ball Valve Compatible w/ stainless steel, Catalyst & Waterborne Materials, 1/4″ NPT(m) x 1/4″ NPT(m), 500 PSI

Stainless steel and PTFE ball valve designed for finishing applications with catalyst, waterborne, and other finishing materials. Features multiple connection options to meet specific application needs with reliable 35 bar (500 PSI) pressure rating.

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.

Stainless steel and PTFE materials are compatible with catalyst, waterborne, and other finishing materials
