In recent years, with the development of mechatronics, electric valves, an important mechanical product, have ushered in an unprecedented market. Electric valves are more economical, safe and reliable in work than traditional valves (manual valves, pneumatic valves). In today's increasing call for environmental protection and safety, electric valves are indispensable. The huge market demand for electric valves is also increasingly high. Electric valves have a wide range of applications, involving petroleum, chemical, electric power, nuclear energy, metallurgy, shipbuilding, light industry, food, municipal and other aspects. As far as the product itself is concerned, electric valves have the advantages of easy assembly, low failure rate, and in line with the automation needs of the industry, which is a more cost-effective choice for the industry. Because of the use of conventional pneumatic valves, it is inevitable to have pipes, solenoid valves and compressors to succeed. The electric valve is driven by a motor, easy to install, and the installation of the electric valve with the factory's original automatic control line can save other costs.

In addition, the opening and closing of the motor drive mode is smooth, without the shortcomings 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, and some low-pressure butterfly valves and gate valves for water supply and drainage valves; The chemical industry mainly uses stainless steel gate valves, globe valves, 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-caliber gate valve mainly used in urban water pipelines, the middle line butterfly valve mainly used in building apartment construction, and the metal sealed butterfly valve mainly used in urban heating. The oil pipeline mainly adopts flat gate valve and ball valve; Pharmaceutical industry mainly uses stainless steel ball valve; The food industry mainly uses stainless steel ball valves.

Electric valve is a new breed of valve industry, so the market prospect of electric valve is very broad, casting enterprises should understand more about this industry, provide casting parts for this industry, to electric valve this emerging industry to drive the development of the casting industry, in order to obtain new development momentum. With the change of market direction, electric valve products have also changed accordingly. For example, with the transfer of oil development to inland oil fields and offshore oil fields, and 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 changes in the field of equipment application. The urban construction system will use a large number of low-pressure electric valves, and to environmentally friendly and energy-saving development, that is, from the past use of low-pressure iron gate valves gradually to environmentally friendly rubber plate valves, balance valves, metal sealed butterfly valves and center line sealed butterfly valves transition, oil and gas transmission projects 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 large-caliber and high-pressure safety valves and reducing valves are needed, and fast opening and closing electric valves are also needed. For the needs of complete sets of projects, the supply of electric valves has been developed from a single variety to multiple varieties and multi-specifications. There is an increasing trend that the electric valves required for an engineering project are all provided by an electric valve manufacturer.

In the future, with the continuous development of market science and technology, electric valves will develop in the direction of high technology content, high parameters, strong corrosion resistance and high life.
