The valve body is a crucial component within a transmission, responsible for shifting between high and low gears. When the vehicle reaches a specific speed for a certain gear, the transmission fluid drives the valve body to automatically shift up or down.
Halnn has been dedicated to the research and development of high-precision cutting tools, significantly enhancing machining efficiency and tool lifespan. This not only reduces machining costs but also provides professional solutions for such machining processes.
