In recent years, with the development of mechatronics integration, electric valves, an important mechanical product, have ushered in a good market. Electric valves are more energy-efficient, safe, and reliable in operation than traditional valves (manual valves, pneumatic valves). In today's increasingly high demand for environmental protection and safety, electric valves are indispensable. The huge market demand for electric valves is also increasing.
The application fields of electric valves are broad, involving petroleum, chemical industry, electricity, nuclear energy, metallurgy, shipbuilding, light industry, food, municipal and other aspects. In terms of the product itself, electric valves have the advantages of easy assembly, low failure rate, and meeting the automation needs of the industry, making them a more cost-effective choice for operators. Because using conventional pneumatic valves requires piping, solenoid valves, and compressors to succeed. The electric valve is driven by a motor, which is easy to install and convenient. The installation of the electric valve can be combined with the factory's existing automatic control circuit, which can save other costs and expenses. In addition, the motor driven mode has a smoother opening and closing without the disadvantage of excessive instantaneous impulse, and the failure rate can be significantly reduced.
The petrochemical industry mainly adopts API standard gate valves, globe valves, and check valves; The power department mainly uses high-temperature pressure gate valves, globe valves, check valves, and safety valves for power plants, 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 large diameter gate valves for urban water pipelines, central line butterfly valves for residential construction, and metal sealed butterfly valves for urban heating; Oil pipelines mainly use flat gate valves and ball valves; The pharmaceutical industry mainly uses stainless steel ball valves; The food industry mainly uses stainless steel ball valves, etc.
Electric valves are a new variety in the valve industry, so the market prospects for electric valves are very broad. Foundry enterprises should learn more about this industry, provide casting parts for this industry, and use the emerging industry of electric valves to drive the development of the casting industry, in order to obtain new development momentum.
With the transformation of market trends, electric valve products have also undergone corresponding changes. For example, with the transfer of oil development to inland and offshore oilfields, and the development of the power industry from thermal power below 300000 kilowatts to thermal power, hydropower, and nuclear power above 300000 kilowatts, electric valve products should also change their performance and parameters accordingly according to changes in equipment application fields.
The urban construction system will adopt a large number of low-pressure electric valves and develop towards environmentally friendly and energy-saving types, gradually shifting from the previously used low-pressure iron gate valves to environmentally friendly rubber plate valves, balance valves, metal sealed butterfly valves, and midline sealed butterfly valves. Oil and gas transmission projects will develop towards pipelining, which in turn requires a large number of flat gate valves and ball valves.
The construction of power stations is developing towards large-scale development, so large diameter and high-pressure safety valves and pressure reducing valves are needed, as well as fast opening and closing electric valves; In response to the needs of complete engineering projects, the supply of electric valves has developed from a single variety to multiple varieties and specifications. All electric valves required for an engineering project are produced by a manufacturer of electric valves.
