GRACO 237531 – Low Pressure Ball Valve, 3/8 NPT(M) x 3/8 NPT(M), Stainless Steel, Catalyst &

GRACO 237531 – Low Pressure Ball Valve Compatible w/ stainless steel, Catalyst & Waterborne Materials, 3/8″ NPT(m) x 3/8″ NPT(m), 500 PSI

Low pressure ball valve designed for finishing applications with stainless steel and PTFE construction. Compatible with catalyst, waterborne, and other finishing materials. Features 3/8″ NPT male connections on both inlet and outlet for versatile installation options.

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
