On May 28, 1983, our first generation leader Mr. Dong founded Yongjia Valve Power Plant as the predecessor of NSEN Valve. After a lapse of 38 years, the company has expanded to 5500m2, and many employees have followed since NSEN inception, which has moved us deeply.

Since NSEN establishment, every small change and every major breakthrough, the NSEN people are still vividly remembered. We can still remember the joy of obtaining China’s “Bidirectional sealing metal seated butterfly valve” national invention patent in 1997, which was the honor of 14 years of continuous research and practice after the establishment of the factory, and also opened a milestone in the future. That is one small step of historical process, we will show some of the company’s major events to everyone in the form of pictures below.

Taking this opportunity, we would like to thank those customers who have always supported us, because with your support, we can continue to develop and progress. At the same time, we will create a better service for customers with a more enthusiastic and full spirit. I hope we can join hands and witness each other’s growth together.
