截止閥在管路中主要作切斷用。抗生素截止閥丶抗生素截止閥設備有以下優點：
    1．  在開閉過程中密封面的摩擦力比閘閥小，耐磨。
    2．  開啟高度小。
    3．  通常只有一個密封面，制造工藝好，便于維修。
    截止閥使用較為普遍，但由于開閉力矩較大，結構長度較長，一般公稱通徑都限制在DN≤200mm以下。（抗生素截止閥丶抗生素截止閥設備）

截止閥的流體阻力損失較大。因而限制了截止閥更廣泛的使用。
    截止閥的種類很多，根據閥桿上螺紋的位置可分：
    一、上螺紋閥桿截止閥
    截止閥閥桿的螺紋在閥體的外面。其優點是閥桿不受介質侵蝕，便于潤滑，此種結構采用比較普遍。
    二、下螺紋閥桿截止閥
    截止閥閥桿的螺紋在閥體內。這種結構閥桿螺紋與介質直接接觸，易受侵蝕，并無法潤滑。此種結構用于小口徑和溫度不高的地方。
    根據截止閥的通道方向，又可分為；直通式截止閥，角式截止閥和三通式截止閥，后兩種截止閥通常做改變介質流向和分配介質用。

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.
