截止阀在管路中主要作切断用。抗生素截止阀丶抗生素截止阀设备有以下优点：
    1．  在开闭过程中密封面的摩擦力比闸阀小，耐磨。
    2．  开启高度小。
    3．  通常只有一个密封面，制造工艺好，便于维修。
    截止阀使用较为普遍，但由于开闭力矩较大，结构长度较长，一般公称通径都限制在DN≤200mm以下。（抗生素截止阀丶抗生素截止阀设备）

截止阀的流体阻力损失较大。因而限制了截止阀更广泛的使用。
    截止阀的种类很多，根据阀杆上螺纹的位置可分：
    一、上螺纹阀杆截止阀
    截止阀阀杆的螺纹在阀体的外面。其优点是阀杆不受介质侵蚀，便于润滑，此种结构采用比较普遍。
    二、下螺纹阀杆截止阀
    截止阀阀杆的螺纹在阀体内。这种结构阀杆螺纹与介质直接接触，易受侵蚀，并无法润滑。此种结构用于小口径和温度不高的地方。
    根据截止阀的通道方向，又可分为；直通式截止阀，角式截止阀和三通式截止阀，后两种截止阀通常做改变介质流向和分配介质用。

The globe valve is mainly used for cutting off in the pipeline. Antibiotic globe valve, antibiotic globe valve equipment has the following advantages: 1. In the process of opening and closing the sealing surface friction than the gate valve small, wear-resistant. 2. Small opening height. 3. Usually only a sealing surface, good manufacturing process, easy to maintain. Globe valves are widely used, but due to large opening and closing torque, long structure length, general nominal size are limited to DN ≤200mm below. (antibiotic globe valve, antibiotic globe valve equipment) globe valve fluid resistance loss is greater. This limits the wider use of globe valves. There are many types of globe valve, according to the position of the stem threads can be divided: 1, on the threaded stem globe valve, the stem of the globe valve threads in the body outside. The utility model has the advantages that the valve stem is not corroded by the medium and is easy to be lubricated. Lower threaded stem globe valve to globe stem threads in body. The stem threads of this construction come into direct contact with the medium and are susceptible to corrosion and are not lubricated. The structure is used in small caliber and low temperature places. According to the direction of the passage of the globe valve can be divided into: Straight-through globe valve, Angle Globe valve and three-way globe valve, the latter two cut-off valve usually do to change the flow direction and distribution of media.
