    截止阀的启闭件是塞形的阀瓣，密封上面呈平面或海锥面，阀瓣沿阀座的中心线作直线运动。阀杆的运动形式，（通用名称：暗杆），也有升降旋转杆式可用于控制空气、水、蒸汽、各种腐蚀性介质、泥浆、油品、液态金属和放射性介质等各种类型流体的流动。因此，这种类型的截流截止阀阀门非常适合作为切断或调节以及节流用。由于该类阀门的阀杆开启或关闭行程相对较短，而且具有非常可靠的切断功能，又由于阀座通口的变化与阀瓣的行程成正比例关系，非常适合于对流量的调节。The globe valve opening and closing is plug valve, sealing the above a plane or cone, disc along the seat of the center line of linear motion. Stem form of exercise, (generic name: non-rising stem), there are also lift rotating bar type can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium such as various types of fluid flow. Therefore, this type of globe valve valve closure is very suitable for as a cut or adjust and throttling. Due to open or close the valve stem travel relatively short, and very reliable cutting function, and due to the change of his seat and disc stroke proportional relationship, is very suitable for the traffic regulation.
