J11W仿美内螺纹截止阀

J11W仿美内螺纹截止阀是一款参照美国标准设计的手动截止阀，核心用于管路中介质的截断或调节。其阀体材质多为不锈钢（“W”代表密封面材质与阀体相同，多为不锈钢），连接方式为内螺纹（“11”中后一位“1”表示内螺纹连接），结构形式为直通式（“11”中前一位“1”表示直通流道）。

 J11W仿美内螺纹截止阀阀门适用压力通常为中低压（如1.6MPa-10MPa），工作温度范围随材质而定，一般为-29℃至425℃，可适配水、油、蒸汽及部分弱腐蚀性介质。密封性能稳定，采用手动旋转阀杆驱动阀芯升降实现启闭，操作简单，广泛应用于石油、化工、冶金、给排水等工业及民用管路系统。

The J11W American-style threaded globe valve is a manually operated globe valve designed with reference to American standards, mainly used for cutting off regulating media in pipelines. Its valve body is mostly made of stainless steel (the "W" indicates that the sealing surface material is the same as the valve body, usually stainless steel), with a female threaded connection (the second "1" in "11" represents female thread connection), a straight-through structure (the first "1" in "11" represents straight-through flow channel).

 This valve is generally suitable for medium low pressure (such as 1.6MPa-10MPa), its operating temperature range varies with the material, usually -29℃ to 425℃. It can be used with water, oil, steam some weakly corrosive media. It has reliable sealing performance, realizes opening closing by manually rotating the valve stem to drive the valve core up down. With simple operation, it is widely used in industrial civil pipeline systems such as petroleum, chemical industry, metallurgy, water supply drainage.
