Our air brake relay valve is engineered to deliver fast, consistent brake response by directing reservoir air to the service brakes of your heavy-duty vehicle. The other essential details of this replacement part are explained below: Dimension Details: This service brake priority relay valve includes four 3/8″ NPT delivery ports, allowing multiple brake chambers to be supplied simultaneously. It features a 3/8″ NPT supply port, 3/8″ NPT control port, and a larger 1/2″ NPT reservoir port for optimal airflow from the air tank. All ports use standard NPT threading for secure, leak-proof installation in commercial vehicle brake systems. Functionality: This relay valve speeds up brake application by sending reservoir air directly to the brake chambers when it receives a signal from the service brake (control port). Instead of waiting for air to travel the full distance from the foot control valve, this relay valve delivers air locally, reducing brake lag and improving stopping performance. The “service brake priority” design ensures controlled, balanced airflow for safe and responsive braking in trucks, trailers, and other heavy-duty equipment.

Uneven braking between axles. Air leaks near control, supply, or delivery ports. Sticking, corrosion, or internal contamination inside the valve. Excessive brake lag during cold starts or under load. Safety Points to Consider While Replacing It: Completely depressurize the air system before removal. Use correct wrenches to avoid rounding the NPT port edges. Apply the appropriate thread sealant (not included) to prevent leaks. Ensure all air lines are routed to the correct labeled ports (Control, Supply, Reservoir, Delivery). After installation, re-pressurize the system and perform a leak test. Conduct a brake application test to confirm quick and balanced air delivery. How to Replace It: Fully drain the air pressure from all tanks. Disconnect the air lines from the old relay valve, marking them if needed for correct reconnection. Remove the old valve from its mounting location and clean the surface. Apply thread sealant to each port and reconnect the supply, reservoir, control, and delivery lines according to port labels. Tighten all NPT fittings securely, but avoid over-torquing. Re-pressurize the system and check for air leaks around every port. Perform several brake applications to ensure a fast, reliable response before returning the vehicle to service. 18 Month Warranty: This product is covered for one year, 100,000 miles after the installation, or 18 months after the purchase, whichever comes first.
