Part No. HB400-60001, FAS proportional valve, also known as transmission proportional valve or retarder proportional valve. It is an electro-pneumatic component matched with Fast transmission, which accurately controls air pressure and adjusts the working state of hydraulic retarder to stabilize braking performance and reduce the risk of brake overheating for heavy trucks on long downhill roads. The valve body is made of high-strength cast aluminum alloy with good sealing and vibration resistance. It fits Shacman Delong X3000, X5000, New M3000S and other heavy truck models. It is an original replacement part for the retarder system. The mounting holes are consistent, can directly replace old parts, widely used for maintenance of long-distance freight heavy trucks.
