Description
What does a relay valve do?
This relay valve plays a critical role in the pneumatic brake system of heavy-duty vehicles by facilitating rapid air pressure transfer through a pilot signal. Built with high-strength components, it ensures reliable braking performance under demanding operating conditions within the air brake circuit.Vehicle and engine compatibility
This component is specifically designed for various Volvo models, including the F10, F12, F7, FL10, FL12, N10, N12, NL10, NL12, B10B, B10M, and B12. It is also fitted to DAF, Faun, Iveco, MAN, Mercedes-Benz, Neoplan, Renault Trucks, and Scania trucks.Installation and maintenance
For proper installation and maintenance, technicians should verify that the port sizes—M22x1.5 for Port 1 and M16x1.5 for Ports 2 and 4—match the vehicle's existing lines. Ensuring the system operates within the maximum 8 BAR pressure limit is essential for maintaining optimal braking response and component longevity.Troubleshooting guidance
Regular inspections of the pneumatic lines and connection points are recommended to prevent pressure drops. Selecting an OE-equivalent part ensures seamless integration with existing WABCO or other system components.OE cross-reference
