Description
What does a relay valve do?
This relay valve serves a critical role in the compressed air brake system of heavy commercial vehicles. By facilitating rapid air pressure transfer triggered by a pilot signal, it ensures precise braking response and system stability under heavy loads. It is constructed from high-strength components to withstand rigorous operational demands.Vehicle and system compatibility
This component is compatible with Scania trucks and is also suitable for various heavy commercial vehicle applications. It serves as an equivalent to WABCO systems, ensuring seamless integration into existing pneumatic architectures. The valve is designed to maintain pressure integrity across its specified operating range.Installation and maintenance
Installation should be performed by a workshop technician to ensure correct mounting on the chassis between the main air reservoir and the brake chambers. When replacing, verify that the port sizes—3/4" - 18 NPTF, 3/8" - 18 NPTF, and 1/4" - 18 NPTF—match the existing system requirements. Regular inspection of the air lines and connection points is recommended to prevent pressure drops.Troubleshooting guidance
