In recent years, with the development of mechatronics, electric valves, an important mechanical product, have ushered in the world's leading market. Compared with traditional valves (manual valves, pneumatic valves), electric valves are more resource-saving, safe and reliable in operation. In today's increasingly demanding environmental protection and safety, electric valves are indispensable. The huge market demand for electric valves is also getting higher and higher. The application fields of electric valves are broad, involving petroleum, chemical industry, electric power, nuclear energy, metallurgy, shipbuilding, light industry, food, municipal and other aspects. As far as the product itself is concerned, electric valves are a cost-effective choice for the industry due to their advantages of easy assembly, low failure rate, and meeting the automation needs of the industry. Because of the use of traditional pneumatic valves, it is inevitable that piping, solenoid valves, and compressors can be successful. The electric valve is driven by a motor, which is easy to install and trouble-free, and the electric valve can be installed with the original automatic control line of the factory, which can save other costs.
In addition, the motor drive method is relatively smooth to open and close, and there is no disadvantage of excessive instantaneous impulse, and the failure rate can be greatly reduced. The petrochemical industry mainly uses API standard gate valves, globe valves and check valves; The power sector mainly uses high-temperature pressure gate valves, globe valves, check valves and safety valves for power stations, as well as low-pressure butterfly valves and gate valves for some water supply and drainage valves; The chemical industry mainly uses stainless steel gate valves, globe valves, and check valves. The metallurgical industry mainly uses low-pressure large-diameter butterfly valves, oxygen globe valves and oxygen ball valves; The urban construction department mainly uses low-pressure valves, such as the large-diameter gate valve mainly used in urban water pipelines, the midline butterfly valve mainly used in the construction of buildings, and the metal sealed butterfly valve mainly used in urban heating. The oil pipeline mainly uses flat gate valves and ball valves; The pharmaceutical industry mainly uses stainless steel ball valves; The food industry mainly uses stainless steel ball valves.
Electric valve is a new variety of valve industry, so the market prospect of electric valve is very broad, foundry enterprises should know more about this industry, provide casting parts for this industry, and drive the development of the foundry industry with the emerging industry of electric valves, so as to obtain new development momentum. With the transformation of the market trend, the electric valve products have also changed accordingly. For example, with the transfer of oil development to inland oilfields and offshore oilfields, as well as the development of the power industry from thermal power below 300,000 kilowatts to thermal power and hydropower and nuclear power above 300,000 kilowatts, electric valve products should also change their performance and parameters according to the changes in equipment application fields. The urban construction system will use a large number of low-pressure electric valves, and to the development of environmental protection and energy saving, that is, from the low-pressure iron gate valve used in the past to gradually shift to the environmentally friendly rubber plate valve, balance valve, metal seal butterfly valve and mid-line seal butterfly valve transition, oil and gas transmission engineering to the direction of pipeline development, which requires a large number of flat gate valves and ball valves. The construction of power stations is developing towards large-scale, so it is necessary to use large-diameter and high-pressure safety valves and pressure reducing valves, as well as quick opening and closing electric valves; In response to the needs of complete sets of projects, the supply of electric valves has developed from a single variety to multiple varieties and specifications. There is a growing trend for electric valves required for a project to be supplied by a single electric valve manufacturer.
In the future, with the continuous development of science and technology in the market, electric valves will develop in the direction of high technology content, high parameters, strong corrosion resistance and long life.
