产品详情
电动法兰截止阀广泛适用于石油化工，火力发电厂等油品、水蒸汽管路上作接通或截断管路中介质的启闭装置。
电动截止阀的特点
1．流体阻力小，其阻力系数与同长度的管段相等。
2．结构简单、体积小、重量轻。电动截止阀
3．紧密可靠，目前闸阀的密封面材料广泛使用塑料、密封性好，在真空系统中也已广泛使用。
4．操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离的控制。
5．维修方便，闸阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便。
6．在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。
7．适用范围广，通径从小到几毫米，大到几米，从高真空至高压力都可应用。
