美标截止阀
产品概述Products overview
美标截止阀主要有API和ASME标准，ASTM,ASTM是材料标准，不是阀门本身的标准；按美国标准设计，制造，生产、检测的截止阀叫做美标截止阀。
American standard cut-off valve mainly include API and ASME standard,ASTM,ASTM material standard,not the standard valve itself;According to the American standard design,manufacturing,production,testing,the cut-off valve American standard cut-off valve.
产品优点Product advantages
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。
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，阀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，球旋转90度时，在进、 出口处应全部呈现球面，从而截断流动。
1.The fluid resistance is small,its resistance coefficient with section of equal length.
2.Simple structure,smal volume,light weight
3.Compact and reliable,the gate valve sealing surface of materials widely used plastic,sealing is good,have been widely used in the vacuum system.
4.Easy to operate,open and dose quickly,from open to close just rotate 90°,is advantageous for the remote control.
5.Easy maintenance structure is simple,sealing ring,which generally remove replacement is more convenient 6.In the fully open or fully closed,the valve body and seat sealing surface and the dielectric isolation,medium through,does not cause the valve sealing surface erosion.
7.Applicable scope is wide,size from small to several millimeters,big to a few meters,from high vacuum to high pressure can be applied,the ball rotate 90 degrees,in the inlet and outlet should be completely present spherical,thereby cutting flow.
