The Air Control Valve Linkage Shaft is a part that is responsible for transmitting the input from the secondary brake control valve to the brake mechanism, allowing for the activation and modulation of the secondary brakes. It is connected to the handle at one end and the air control valve on the other end, which modulates the braking force applied to the secondary brakes.Attributes:• Allows for quick and responsive transmission of braking function• Withstand the forces and stresses associated with brake actuationApplications:The Air Control Valve Linkage Shaft serves as the connective element to the secondary brake control valve and the brake mechanism that allows for enough braking force applied to the secondary brake function.
