Specific analysis of electric valve:
With the continuous development of science and technology, China's electric valve product market is also developing in the direction of high technology content, high parameters, and strong corrosion resistance. According to the analysis of domestic and foreign electric valve technology and the analysis of domestic and foreign electric valve market demand, the development trend and investment direction of high-tech industrial electric valves used in various industries and electric valve industry in recent years are researched, as follows:
1. Valves for oil and natural gas wellhead devices
Valves for oil and gas wellhead installations are mainly single or double rams, forged steel parallel gate valves with diversion holes or no diversion holes, mud valves, angle choke valves, and oil field special parallel gate valves that meet the American API6A standard. Type regulating valve, special straight-through check valve for oil field, parallel gate valve for water injection/polymer, clamp type parallel gate valve, check valve.
2. Valves for long-distance oil and natural gas pipelines
The valves for long-distance oil and natural gas pipelines are mainly single gate or double gate, flat gate valve with diversion hole or no diversion hole in accordance with the American API6D standard; forged steel or cast steel three-body type, top-loading type or all-welded type Fixed ball valve oil seal or pressure balance plug valve; swing or butterfly check valve, ball check valve; pigging valve, etc.
