Product Introduction

The brake master valve is a core component of the air brake control system in heavy-duty trucks, trailers, and buses. It regulates and distributes compressed air to different brake circuits, ensuring precise braking response and reliable vehicle safety. This valve is typically mounted in the driver’s control system and directly connected to the foot brake pedal or hand brake mechanism.

Our brake master valves are compatible with various models from SINOTRUK (HOWO), SHACMAN, FAW, Dongfeng, Foton, and can replace popular configurations such as WABCO-type dual-circuit valves. Designed for durability, accurate control, and long service life.
