電動法蘭截止閥廣泛適用于石油化工，火力發(fā)電廠等油品、水蒸汽管路上作接通或截斷管路中介質(zhì)的啟閉裝置。

電動截止閥的特點
　　
　　1．流體阻力小，其阻力系數(shù)與同長度的管段相等。
　　
　　2．結(jié)構(gòu)簡單、體積小、重量輕。電動截止閥
　　
　　3．緊密可靠，目前閘閥的密封面材料廣泛使用塑料、密封性好，在真空系統(tǒng)中也已廣泛使用。
　　
　　4．操作方便，開閉迅速，從全開到全關(guān)只要旋轉(zhuǎn)90°，便于遠距離的控制。
　　
　　5．維修方便，閘閥結(jié)構(gòu)簡單，密封圈一般都是活動的，拆卸更換都比較方便。
　　
　　6．在全開或全閉時，球體和閥座的密封面與介質(zhì)隔離，介質(zhì)通過時，不會引起閥門密封面的侵蝕。
　　
　　7．適用范圍廣，通徑從小到幾毫米，大到幾米，從高真空至高壓力都可應(yīng)用。
