截止阀[GLOBE VALVE]

截止阀是一种常用的截断阀,主要用来接通或截断管路中的介质,一般不用于调节流量．截止阀适用压力、温度范围很大,但一般用于中、小口径的管道．

globe valve as one of the cut-off valve is a common valves mainly used to connect or disconnect the line of medium, generally not for regulating flows. globe valves apply pressure, high temperature range, but are generally used for medium and small-calibre pipeline
