Williams Controls Treadle Valve Assembly
Achieve smoother, more predictable braking response with the Williams Controls Treadle Valve Assembly. This cab-mounted assembly converts driver pedal force into modulated air pressure, controlling how braking force is applied across the system. As pedal position changes, it meters air delivery to match driver input, allowing gradual or firm braking as needed. Built as a replacement for WM472A series valves, this Williams Controls 113218 assembly restores proper pedal feel and braking control in heavy-duty truck air brake systems.
