It mounts in a three‑hole panel cutout and uses 1/4″ NPT ports to supply or exhaust air from the spring brake chambers. The valve is operated by pulling or pushing the knob, giving the driver or technician a direct way to control the park brakes without relying on the tractor’s dash valve. Replace it when the valve sticks, leaks, or no longer holds the knob in the applied or released position.
