Air valves are critical components within a vehicle's air brake system, responsible for controlling the flow of compressed air to actuate braking mechanisms in both passenger cars and commercial vehicles. Located throughout the air lines and brake chambers, these valves regulate air pressure to the brakes, enabling functions like service braking, parking braking, and trailer control. They ensure reliable and responsive brake operation, contributing directly to vehicle safety. Examples in this category include relay valves, quick release valves, and control valves. We carry air valves from leading manufacturers such as Wabco, as well as specific MAN parts like MPN 51158015173 and 81.51201-0416, ensuring compatibility and performance.
