Product description

This 3-Position Valve is specifically configured for the Long Arm version of the Coats Robo-Arm helper device. It serves as the primary control interface for the technician to manipulate the helper arm's vertical and horizontal movements during the mounting of stiff, low-profile, or run-flat tires. Because helper arms are used to exert significant downward pressure, the control valve must be able to handle high-frequency operation and maintain an airtight seal in all positions. Over time, internal wear can lead to "drifting" of the arm or a lack of responsiveness, which can compromise both safety and rim protection. Replacing the valve with this dedicated long-arm unit ensures that the helper device operates with the precision and speed required for modern wheel service. It is built to withstand the rigors of a high-volume professional tire shop environment.
