What does an exhaust brake valve do?

This exhaust brake valve plays a critical role in the engine braking system by controlling the flow of exhaust gases to assist in vehicle deceleration. Constructed with high-strength components, it is designed to withstand the intense thermal and pressure fluctuations typical of heavy commercial vehicle operation.

Compatible Volvo models and engines

The component is specifically fitted to Volvo FM series trucks, including models such as the FM 300, FM 340, FM 370, FM 380, FM 390, FM 400, FM 410, FM 420, FM 440, FM 450, FM 460, and FM 480. It is also compatible with Volvo FM11 engines featuring the D11B engine type and adheres to EURO 6 emission standards.

Installation and maintenance guidance

When performing maintenance or replacement, technicians should verify that the valve aligns with the specific engine's emission standard and mounting configuration. Proper installation ensures optimal braking force and prevents premature wear within the exhaust manifold system.

Troubleshooting and selection

Regular inspections of the braking system components can help prevent unexpected downtime. For accurate fitment verification across different engine variants, always check the compatibility list.
