美國歐可電動閥門就是用電源來驅動電動執行器進而驅動閥門來進行節流的調節閥，它是工業自動化過程控制中的重要執行單元儀表。隨著工業領域的自動化程度越來越高，正被越來越多的應用在各種工業生產領域中。電動閥門與傳統的氣動閥門相比具有明顯的優點：節能（只在工作時才消耗電能），環保（無碳排放），安裝快捷方便（無需復雜的氣動管路和氣泵工作站）工作電源：AC22V 380V等電壓等級。電動閥門通過接收工業自動化控制系統的信號（如：4~20mA）來驅動閥門改變閥芯和閥座之間的截面積大小控制管道介質的流量、溫度、壓力等工藝參數。實現自動化調節功能。
The United States of America Ou electric valve is to use the power to drive the electric actuator to drive the valve to throttle valve, it is industrial automation and process control in the execution unit instrument. With the field of industrial automation degree is more and more high, being more and more used in various industrial production areas. Electric valve pneumatic valve compared with the traditional has obvious advantages: saving energy ( power consumption only when at work can ), environmental ( no carbon emissions ), quick and convenient installation ( without the need for complex pneumatic pipeline and pump station ) working power supply: AC22V380V voltage grade. Electric valve through the receiving industrial automation control system signal ( such as:4~20mA ) to drive the valve core and a valve seat valve change between the cross-sectional area of the flow of media channels, control of temperature, pressure and other parameters. Realization of automatic regulation function.
