Normally STOP means nothing good, but no train in China stops without Huatong.
The high-performance ABS pneumatic braking system for trains (with our highfrequent ABS-brake-valve as heart piece) has during more than 25 years never failed to stop any train safely in the best possible quickly way. We believe that kind of STOP says something good about our quality and engineering skills. Till today this special pneumatic valve was continuously further developed to continue to resist hardest conditions such as working with unprocessed and wet pressured air on the Qinghai-Tibet Railway in polar climate with up to minus 50 degrees Celsius in over 5000 meters over sea-level with great enduring slopes which sets highest requirements to our valve. Well, it has never stopped working, but always reliable stops or slows the train wherever demanded.
The security, reliability and constancy of the control valves for the brake control system have reached the international advanced standard. They valves are produced by our company only interiorly, accouding for about 65% market quotient, making great contribution to accelerating of railway in our country.
