It automatically shuts off air to the trailer in the event of a sudden pressure loss, preventing complete loss of braking on the tractor. You typically replace this valve when it leaks internally or externally, fails to shut off air during a trailer breakaway, or causes delayed brake application and release. This particular unit includes a built-in quick release function and a dust shield for the exhaust port.
