Who knows the state-run Suzhou 526 factory?

Suzhou Iron Works was first changed to Suzhou Valve Works, which was also called 526 Works because it was a military enterprise code 526. After the reform and opening up, it was changed to Suzhou Valve Factory of China National Nuclear Corporation and Suzhou Valve Factory of China National Nuclear Corporation, and then listed in Shenzhen. The production base is divided into two areas: CNNC Suzhou Valve Technology Industrial Co., Ltd., and the controlling party of the original valve factory is CNNC Suzhou Valve Co., Ltd., which is basically the case.
