电动阀是以电动机作为启闭阀门的动力，用于比较大型的阀门，的电动阀，可以用于工艺上的流量控制。
    电动阀具备装配容易、故障率低以及符合业界自动化需求的优点，是业者较划算的选择。因为使用一般传统气动阀，免不了要有配管、电磁阀及压缩机等才能匹配，而电动阀是以马达驱动，安装简易省事，且电动阀安装配合工厂原有的自控线路即可，可节省其他成本支出。此外，以马达驱动方式开闭较平顺，无瞬间冲力过大的缺点，故障率可大幅降低,不少人都认为电动阀贵，使用成本高，其实不然，如果以整体计算，传统阀要加上许多配件及管路安装，价格并未占优势，反而要承担较多的保养费.所以电动阀的前景是比较广阔的。 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.
