Product description

This 3-Position Valve is designed for the Roller Arm helper systems found on select Coats tire changers. The roller arm plays a crucial role in pressing the tire bead into the wheel's drop center, and this valve provides the necessary pneumatic control for its extension and pressure application. In a professional shop environment, the internal components of pneumatic valves are susceptible to wear from moisture and particulates in the air lines, which can lead to sticking or pressure leakage. A failing valve can cause the roller arm to lose its effectiveness, potentially leading to beads popping out or damage to the tire's inner liner. By installing this direct replacement valve, you restore the precise pneumatic command required for safe and efficient tire installation. It is built to the same rigorous standards as the original equipment to ensure long-term reliability in high-volume settings.
