近年來隨著機電一體化的發(fā)展，電動閥門這一重要的機械產(chǎn)品迎來了前所未有的市場。電動閥門比傳統(tǒng)的閥門(手動閥門、氣動閥門)在工作上更加節(jié)源、安全可靠。在環(huán)保和安全的呼聲越來越高的今日，電動閥門是不可或缺的。巨大的市場需求對電動閥門的要求也越來越高。
 

　　電動閥門的應用領(lǐng)域廣闊，涉及石油、化工、電力、核能、冶金、船舶、輕工、食品、市政等方面。就產(chǎn)品本身而言，電動閥門具備裝配容易、故障率低，以及符合業(yè)界自動化需求的優(yōu)點，是業(yè)者較劃算的選擇。因為使用一般傳統(tǒng)氣動閥，免不了要有配管、電磁閥及壓縮機等才能成功。而電動閥門是以馬達驅(qū)動，安裝簡易省事，且電動閥安裝配合工廠原有的自控線路即可，可節(jié)省其他成本支出。此外，以馬達驅(qū)動方式開閉較平順，無瞬間沖力過大的缺點，故障率可大幅降低。

　石化行業(yè)主要采用API標準的閘閥、截止閥和止回閥;電力部門主要采用電站用高溫壓閘閥、截止閥、止回閥和安全閥及一部分給排水閥的低壓蝶閥、閘閥;化工行業(yè)主要采用不銹鋼閘閥、截止閥、止回閥。
 

　 冶金行業(yè)主要采用低壓大口徑蝶閥、氧氣截止閥和氧氣球閥;城市建設部門主要采用低壓閥，如城市自來水管道主要采用的大口徑閘閥，樓寓建設主要采用的中線蝶閥，城市供熱主要采用的金屬密封蝶閥等;輸油管線主要采用平板閘閥和球閥;制藥行業(yè)主要采用不銹鋼球閥;食品行業(yè)主要采用不銹鋼球閥等。
 

　　電動閥門是閥門行業(yè)的新品種，因此電動閥門的市場前景是非常廣闊的，鑄造企業(yè)應多了解這個行業(yè)，為這個行業(yè)提供鑄造件，以電動閥門這個新興的行業(yè)來帶動鑄造行業(yè)發(fā)展，以獲得新的發(fā)展動力。

In recent years, as the development of mechatronics, electric valvewhich is one of the most important mechanical products ushered in ahitherto unknown market. Electric valve than conventional valves(manual valves, pneumatic valves) at work more source saving, safe and reliable. In environmental protection and safety is more and more high today, electric valve is indispensable. The huge market demand requirements of electric valve is also more and more high.

The application field of electric valve is broad, involved in petroleum, chemical, electric power, nuclear power, metallurgy,shipbuilding, light industry, food, municipal etc.. On the product itself, the electric valve fitted with easy, low failure rate, and the advantage of meeting of industry automation needs, is the industry more cost-effective choice. Because the use of conventionalpneumatic valve, inevitably a piping, solenoid valve and the compressor can be successful. While the electric valve is a motor-driven, easy install, and electric valves installed with the original factory lines can be controlled, can save other costs. In addition, the motor drive open and close more smoothly, without an excessive momentum shortcomings, failures can be substantially reduced rate.

Petrochemical industry mainly uses the API standard gate valve,globe valve and check valve; power sector mainly adopts high pressure power station gate valve, globe valve, check valve and safety valve and a part of water supply and drainage valve with low pressure butterfly valve, gate valve; chemical industry mainly usesstainless steel gate valve, globe valve, check valve.

Metallurgical industry mainly uses low-voltage large-diameterbutterfly valve, oxygen valve and the oxygen valve; urban construction departments mainly adopts low pressure valve, such as large diameter gate of city tap water pipe is mainly adopted, the center line butterfly valve mainly by building construction, urban heating mainly adopts the metal sealing butterfly valve; pipelinemainly uses the flat gate valve and ball valve; the pharmaceutical industry mainly uses stainless steel ball valve; the food industry mainly uses stainless steel ball valve.

The electric valve is a new variety of the valve industry, so theelectric valve market prospect is very broad, foundry enterprises should be more understanding of the industry, provide the castingfor the industry, with the electric valve in the new industry to drive the development of foundry industry, in order to obtain newdevelopment power.
