Description
The KN28510 Trailer Relay Valve RG-2 is a genuine heavy-duty relay valve designed for air brake systems on trailers. This RG-2 style relay valve controls the flow of air from the supply tank to the brake chambers, allowing for quick and balanced brake application across all axles.
Built for durability and consistent performance, the KN28510 is engineered to withstand the vibration, pressure cycles, and harsh conditions typical of commercial trailer use in South Texas. A properly functioning relay valve is critical for safe braking, especially on heavy or multi-axle trailers.
