Description

What does a relay valve do?

This relay valve is a critical component within the pneumatic brake system of heavy commercial vehicles. It functions by facilitating rapid air pressure transfer triggered by a pilot signal, ensuring efficient braking performance. Built with high-strength components, it is designed to withstand the rigorous operating conditions found in heavy-duty vehicle applications.

Compatible Volvo models and engines

This specific unit is engineered for several Volvo models, including the F7, F10, F12, FL10, FL12, N10, N12, NL10, NL12, B10B, B10M, and B12 series. It is also fitted to other trucks such as DAF, Iveco, MAN, Mercedes-Benz, Renault Trucks, and Scania. This part is compatible with WABCO systems.

Installation and technical specifications

When performing maintenance or replacement on the pneumatic braking system, technicians should verify the port sizes to ensure correct installation. This valve features a M22x1.5 port at Port 1 and M16x1.5 ports at Port 2 and Port 4. Ensuring all connections are secure helps maintain the required 10 BAR maximum pressure integrity.

Maintenance guidance

Regular inspection of the air lines and signal connections can prevent pressure drops in the braking circuit. For optimal performance in heavy commercial vehicle fleets, always consult your authorized distributor to verify specific fitment requirements.
