Relevant information: The installation of pneumatic butterfly valves at various stages requires that the pneumatic on-off ball valves must follow the path of innovative scientific and technological development in the future. The fundamental thing is how to eliminate mechanical failures of electric ball valves. What are the classification of electric ball valves? What are the installation details of electric on-off butterfly valves

Although the electric ball valve has played an important role in promoting domestic construction, the valve products produced in China at present have low technical content, most of them are labor intensive products, and few of them are at the international leading level. At present, there are more than 5000 enterprises producing spherical valves, but only 7 of them have an annual sales amount of more than 50 million yuan, There are only three enterprises with an annual sales amount of more than 100 million yuan, none of which can exceed 200 million yuan. In terms of market share, only one enterprise has reached 1%, and the share of other enterprises is less than 1%. It is difficult for such enterprises to gain a foothold in the market, let alone have a greater shock. They will be in an absolute disadvantage when competing with international enterprises, and will become more and more difficult, In order to change the status quo of the above industries, in addition to focusing on their own growth and development, it is also necessary to carry out alliances and cooperation between enterprises, pool industry capital through mergers and reorganization, complete the initial expansion and development, and constantly improve their possession, so as to be in a superior position in internal and external competition.
