Product Overview

Graco 125188 Ball Valve 2-Way 1-1/4 NPT 6000 PSI Stainless Steel is a genuine Graco high-pressure two-way ball valve engineered for on/off fluid control in industrial spray and dispense applications. With a 6000 PSI pressure rating and 1-1/4" NPT male and female connections, it integrates directly into Graco high-pressure fluid lines for isolation of system components or pressure relief during maintenance. The stainless steel body provides resistance to corrosion and chemical attack from aggressive coatings, solvents, and process fluids. Ball valves must always be operated in the fully open or fully closed position and must not be used to throttle fluid flow.

Frequently Asked Questions

No. Ball valves must be used in the fully open or fully closed position only. Using the valve to throttle flow causes rapid wear of the ball and seat, leading to premature valve failure.

Stainless steel provides superior resistance to corrosion from aggressive industrial fluids including solvent-based coatings, waterborne materials, and catalysts commonly used in Graco high-pressure spray systems.

The Graco 125188 is rated to a maximum operating pressure of 6000 PSI (6 ksi), making it suitable for high-pressure Graco spray foam, polyurea, and pump system fluid line applications.
