6886834 Volvo F10 TD102 Relay Valve Equivalent

What does a relay valve do?

This relay valve serves as a critical component within the compressed air brake system, facilitating rapid air pressure transfer triggered by a pilot signal. Engineered for high-performance reliability, it ensures the efficient delivery of pneumatic pressure to the brake chambers, maintaining consistent braking force under demanding conditions.

Vehicle and engine compatibility

This specific unit is compatible with Volvo F10 trucks equipped with TD102 engines. It is designed to meet the rigorous demands of heavy commercial vehicle service, ensuring seamless integration within the pneumatic architecture of the vehicle's braking system.

Installation and maintenance

Installation requires attention to the specific port sizes: Port 1 is M22x1.5, while Ports 2 and 4 are M16x1.5. Technicians should ensure all connections are secure and check that the system does not exceed the maximum operating pressure of 8 bar during testing or standard operation.

System performance and testing

Regular inspection of the valve and its connections can help prevent air leaks and ensure optimal response times in the braking circuit.
