303.01.0019 Relay Valve for Volvo Trucks

This relay valve serves as a critical component within the compressed air brake system, facilitating rapid air pressure transfer triggered by a pilot signal. Built with high-strength components, it ensures precise modulation and reliability under heavy-duty operating conditions to maintain optimal braking performance.

This part is specifically engineered 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, Iveco, MAN, Mercedes-Benz, Scania, and Renault Trucks. The valve is compatible with WABCO systems and provides reliable service for heavy commercial vehicle fleets.

For proper maintenance, technicians should inspect all M22x1.5 port connections and ensure the valve operates within the 10 BAR maximum pressure limit. Regular checks of the pneumatic lines and seals are recommended to prevent pressure drops in the braking circuit.

When replacing this component, ensure the new unit matches the existing port configuration to maintain system integrity and safety during operation.
