These parts are essential components within the pneumatic braking programs of towed automobiles. They regulate the movement of compressed air, enabling the operation of brakes and different air-powered capabilities on semi-trailers, full trailers, and different towable tools. A standard instance is a relay valve, which quickens brake utility by delivering air from an area reservoir to the brake chambers, relatively than relying solely on the tractor’s air provide.
The correct perform of those valves ensures protected and environment friendly braking, stopping accidents and minimizing put on on brake parts. Traditionally, developments in valve design have paralleled enhancements in total braking know-how, resulting in extra responsive and dependable programs. Their implementation has been a vital issue within the discount of freeway accidents involving giant automobiles.
