Description

What does a relay valve do?

This relay valve plays a critical role in the pneumatic braking system by managing air pressure distribution to ensure consistent braking performance. Built with high-strength components, it facilitates the rapid response required for heavy commercial vehicle safety during deceleration.

Vehicle and engine compatibility

This specific model is engineered for use in Volvo B12 trucks equipped with D12A engines. It serves as a reliable replacement part within the air brake system, ensuring that pressure regulation meets strict operational standards for heavy-duty service.

Installation and maintenance

Installation requires careful attention to the M22x1.5 port connections to prevent air leaks. Technicians should verify that the system pressure does not exceed the 10 BAR maximum rating during testing to maintain the integrity of the pneumatic circuit.

Maintenance and troubleshooting

Regular inspections of the valve ports and seals are recommended to prevent moisture ingress or pressure drops. Maintaining clean air supply lines helps extend the service life of this high-performance component.

OE cross-reference

303.01.0001 (Relay Valve Relay Valves) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 384909.
