WM472 - Treadle Valve
Product Brand: Williams Controls
Used in industrial and vehicular applications where a three-way, compensating treadle valve is required.
The WM-472 series valves are used in industrial and vehicular applications where a three-way, compensating treadle valve is required. These treadle valves are primarily installed in relay-type brake systems. Mounted through the floor of the operator’s compartment, the valve sub-assembly can be rotated on 90° increments for plumbing convenience.
As the operator depresses the pedal, the exhaust port closes and the supply port opens to allow delivery. The valve subassembly modulates the output in relation to the position of the pedal. When the pedal is released, the outlet pressure is discharged through an exhaust port located in the valve bottom.
