電動(dòng)閥是以電動(dòng)機(jī)作為啟閉閥門的動(dòng)力，用于比較大型的閥門，高級的電動(dòng)閥，可以用于工藝上的流量控制。電動(dòng)閥具備裝配容易、故障率低以及符合業(yè)界自動(dòng)化需求的優(yōu)點(diǎn)，是業(yè)者較劃算的選擇。因?yàn)槭褂靡话銈鹘y(tǒng)氣動(dòng)閥，免不了要有配管、電磁閥及壓縮機(jī)等才能匹配，而電動(dòng)閥是以馬達(dá)驅(qū)動(dòng)，安裝簡易省事，且電動(dòng)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(dá)驅(qū)動(dòng)方式開閉較平順，無瞬間沖力過大的缺點(diǎn)，故障率可大幅降低,不少人都認(rèn)為電動(dòng)閥貴，使用成本高，其實(shí)不然，如果以整體計(jì)算，傳統(tǒng)閥要加上許多配件及管路安裝，價(jià)格并未占優(yōu)勢，反而要承擔(dān)較多的保養(yǎng)費(fèi).所以電動(dòng)閥的前景是比較廣闊的。

　　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.
