Relay valves are primarily used on long wheelbase trucks, tractors, buses, and commercial vehicles to apply and release rear axle service or parking brakes. They graduate, hold, or release air pressure from brake chambers upon signal pressure from the service brake valve. The R-8 design is ideal for applications requiring spring-actuated parking brake control with anti-compounding features.

This valve replaces OEM part numbers 286370N, 286370RX, and Meritor R955286370N. Manufactured to meet or exceed original equipment specifications in form, fit, and function.
