Shanghai with its unique charm of the sea, produced an international well-known brands of products, automatic control brass ball valve system is one of the country's automation industry has made a special contribution. Shanghai Chongming Island, Shanghai Automation Instrument Factory 7 (formerly Telecom Instrument Factory Chongming), as early as the beginning of production in 1966, regulating valve, and has become a control valve, one of the industry's first factory. After reform and opening up the eighties, more rapid development, Shanghai has set up a brilliant instrumentation companies, such as Shanghai Dacheng Factory size of more than 20, ranging from professional valve manufacturer. Chongming Island, the regulating valve nearly 2 million in annual sales, the initial formation of the industrial development of Georgia.
