截止阀用阀瓣作启闭件并沿阀座轴线移动，以实现启闭动作的阀门。截止阀主要用于截断流体，在对调节性能要求不高的场合也可用于调节流量。截止阀是管道上常用的一种阀门。常见的截止阀阀体流道形式有直通式、直流式和直角式3种（图1）。直通式截止阀(图2)的流体阻力较大,因阀体形状近似球体，所以习称球形阀。为了减小流体阻力,后又出现直流式（Y型）截止阀和直角式截止阀。直流式多用于含固体颗粒或粘度大的流体。直角式用于高、中压力的直角型管道。 截止阀的密封面主要有平面和锥面两种。锥面密封的接触面宽度比平面密封的小，所需密封力小，密封性较易保证，启闭力也低得多，大多用于高压场合。为了减小启闭力,已研制出高压平衡式截止阀（图3）。它采用压力平衡式阀瓣。流体从阀瓣下部通过小孔进入阀瓣上部，能抵消流体作用于阀瓣上的大部分轴向力。截止阀的主要优点是：开启高度小（一般为阀座通孔直径的1/4）,因而开关较迅速；启闭过程中密封面间一般无相对滑动，故不易磨损擦伤；阀瓣和阀座的维修方便。缺点是启闭力和流体阻力较大，因此不能做得太大，一般中、低压截止阀的公称通径不大于250毫米,高压截止阀不大于150毫米。
