It speeds up brake release by rapidly exhausting air from spring brake chambers and prevents compounding, where service and spring brakes apply simultaneously, which can damage brake components. It replaces separate quick release and double check valves, simplifying spring brake control circuits on trucks and tractors. The internal diaphragm and disk are oil-resistant for extended service life.
