電動閥是以電動機作為啟閉閥門的動力，用于比擬大型的閥門，高級的電動閥，可以用于工藝上的流量把持。
電動閥具備裝配輕易、故障率低以及符合業界主動化需求的長處，是業者較劃算的選擇。由于應用一般傳統氣動閥，免不了要有配管、電磁閥及壓縮機等才干匹配，而電動閥是以馬達驅動，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，可節儉其他本錢支出。此外，以馬達驅動方法開閉較平順，無瞬間沖力過大的毛病，故障率可大幅下降,不少人都認為電動閥貴，應用本錢高，實在不然，假如以整體盤算，傳統閥要加上很多配件及管路安裝，價格并未占上風，反而要承擔較多的保養費.所以電動閥的前景是比擬廣闊的。

Electric valves open and close valves on the electric motors as a driving force for the larger valves, electric valves, the processes can be used to control the flow.Electric valves fitted with easy, low failure rate in the industry and the advantages of automation needs is more economical choice operators. Because of the use of general traditional pneumatic valves, inevitably a ticket pipes, and electromagnetic valves, compressors can match, and electrical devices are motor-driven, easy to install, and the installation of electrical devices with the original robotic factory line will be able to reduce other costs. In addition to motor-driven approach to turn more smoothly, without an excessive momentum shortcomings, failures can be substantially reduced rate, many people believe that your electric valves, the use of high cost, but in fact it is not, if a holistic basis, and many accessories to traditional valves and the installation of pipelines, the price is not dominant, Instead, they will assume more maintenance. Therefore, the prospects for electrical devices are relatively broad.
