In recent years, with the development of electromechanical integration, an important mechanical products of electric valve ushered in the unprecedented market.Than traditional electric valve valve (manual valve, pneumatic valve) source more day on the job, safe and reliable.In the call for environmental and safety is higher and higher today, electric valve is indispensable.The huge market demand is becoming more and more high to the requirement of electric valve.Electric valves wide application field, involves the petroleum, chemical industry, electric power, nuclear power, metallurgy, shipbuilding, light industry, food, municipal, etc.In terms of the product itself, the electric valve for easy assembly, low failure rate, and can meet the demand of industry automation, the advantages of the industry is more cost-effective option.Because of the use of general traditional pneumatic valves, not avoid such as piping, solenoid valve and the compressor to be successful.In motor drive and electric valve, simple and convenient installation, and electric valve installation can cooperate factory original control circuitry, other costs can be saved.

　　In addition, the open and close more smooth in motor drive way, without too much momentum moment failure rate can be greatly reduced.Petrochemical industry mainly USES the API standard gate valve, globe valve and check valve;Power sector mainly adopts power station with high temperature and pressure gate valve, globe valve, check valve and relief valve, and part of the water supply and drainage valve of low pressure butterfly valve, gate valve;The chemical industry mainly adopts stainless steel gate valve, globe valve, check valve.Metallurgical industry mainly adopts low voltage large diameter butterfly valve, oxygen cut-off valve and ball valve;Urban construction department mainly adopts low-pressure valve, such as urban tap water pipeline mainly adopts large-diameter gate, building construction mainly adopts center line butterfly valve, city heating mainly adopts the metal sealing butterfly valve, etc.;Pipeline mainly adopts flat gate valve and ball valve;The pharmaceutical industry mainly adopts stainless steel ball valve;The food industry mainly adopts stainless steel ball valve and so on.

　　New varieties of electric valve is the valve industry, so the electric valve market prospect is very broad, foundry enterprises should know more about the industry, provide casting parts for the industry, the emerging industry of electric valve to driving the development of foundry industry, in order to obtain the new development momentum.With the transformation of the direction of the market, products of electric valve also change accordingly.For example, as oil development to the mainland oil fields and the transfer of offshore oil field, as well as the electric power industry from 300000 kw to 300000 kw thermal power under the above of the thermal power and hydropower and nuclear power development, electric valve products should be based on equipment application domain changes to change its properties and corresponding parameters.And the urban system will use a large number of low voltage electric valve, and to the development of environmental protection and energy-saving, namely by the use of low pressure iron gate toward environmental protection rubber sheet, balance valve, the transition metal sealing butterfly valve and the midline sealing butterfly valve, oil and gas engineering to develop in the direction of pipelining, it requires a lot of flat gate valve and ball valve.Power plant construction toward large-scale development, so the need of large diameter and high pressure relief valve and pressure reducing valve, at the same time also need quick opening and closing electric valves;Aiming at the need of package engineering and supply of electric valve by a single species to more varieties and specifications.Required for a project of electric valve, provided by a manufacturer of electric valve all trend is more and more big.

　　Future electric valves with the continuous development of science and technology market, to high technology content, high parameter, strong corrosion resistance, high life direction.
