We are a valve factory in Nanjing China, where 50 miles away from Beijing. We can produce all kinds of valves and we  are also the seller for all the China?????alve brand.
We make high-performance check valves that will double your Cv?????f you are looking for the lowest possible pressure loss then our resilient hinged double disc valves are what you need.
Our unique, air-foil designed wing support conditions the flow profile, resulting in a more laminar, less turbulent flow, thus extending the life of the valve. Our valves consistently out-perform all other products on the market today.
A protective coating secures our valves against normal atmospheric corrosion and enhances appearance, making priming and painting unecessary.
Each of our valves is individually inspected and tested to ensure performance. Most manufacturers will check only random valves. We test every, single one.
