Description
The KN30400 Trailer Relay Valve (KN) is a robust, high-performance relay valve engineered for trailer air brake systems. It controls the delivery of compressed air from the supply reservoir to the brake chambers, allowing for rapid and balanced brake application across all axles when the driver applies the brakes.
Built for durability and consistent performance under demanding conditions, the KN30400 is designed to withstand vibration, pressure cycling, and the harsh South Texas environment. A properly functioning relay valve is essential for safe braking performance, especially on heavy or multi-axle trailers.
This valve is a direct replacement commonly used on air brake equipped utility trailers, flatbeds, equipment haulers, and heavy-duty ranch trailers.
