100% OEM-Spec Fitment: Manufactured strictly to Shacman Delong OEM standards, featuring precise mounting interfaces and airflow dimensions for a seamless fit on F2000, F3000, and X3000 series heavy-duty trucks.

High-Temperature Alloy & Superior Airtightness: Constructed from high-quality, heat-resistant cast iron or cast steel, the valve body withstands the high temperatures and pressures of engine exhaust; its tight seal prevents leakage, ensuring stable, long-term operation.

Rapid Response & Efficient Braking: The pneumatic actuator responds quickly to precisely control exhaust backpressure, delivering powerful auxiliary braking during long descents or continuous deceleration, thereby significantly enhancing driving safety.

Protects Main Braking System & Reduces Costs: By providing efficient auxiliary deceleration, it effectively minimizes wear and thermal fade on service brakes (brake pads and discs), extends the lifespan of the main braking system, and lowers truck maintenance costs.

Robust, Durable & Vibration-Resistant: The rigid, one-piece cast structure offers excellent vibration and wear resistance, easily handling the high-intensity demands of harsh operating environments such as mining sites, mountainous roads, and long-haul transport.
