GRACO 237533 – Low Pressure Ball Valve, 3/8 NPSM(M) x 3/8 NPT(M), Stainless Steel (316), Catalyst &

GRACO 237533 – Low Pressure Ball Valve Compatible w/ stainless steel, Catalyst & Waterborne Materials, 3/8″ NPSM(m) x 3/8″ NPT(m), 500 PSI

GRACO 237533 Ball Valve designed for finishing applications with 3/8″ NPSM(M) x 3/8″ NPT(M) connections. Features stainless steel and PTFE materials for compatibility with catalyst, waterborne, and other finishing materials. Built for high-pressure operation at 35 bar (500 PSI) with versatile connection options to meet specific finishing needs.

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
