一、进口压力自紧式锻钢闸阀产品介绍：

进口压力自紧式锻钢闸阀，Pressure self tightening type forged steel gate valve，是指采用压力自紧式阀盖，按这种设计形式设计的阀门，其阀体与阀盖螺纹连接，内压自密封环密封的闸阀。

美国威盾VTON锻钢高压闸阀适用于Class150～2500 、工作温度 -29～425℃（碳钢）或 -29～500℃（不锈钢）的小口径管路上，用于截断或接通管路中的介质，选用不同的材质，可分别适用于水、蒸汽、油品、硝酸、醋酸、氧化性介质、尿素等多种介质。

Pressure self tightening type forged steel gate valve refers to a gate valve designed with a pressure self tightening valve cover. The valve body is threaded to the valve cover and sealed with an internal pressure self sealing ring.

VTON forged steel high-pressure gate valve is suitable for small diameter pipelines with a working temperature of -29-425 ℃ (carbon steel) or -29-500 ℃ (stainless steel) in Class 150-2500. It is used to cut off or connect the medium in the pipeline. Different materials are selected and can be used for various media such as water, steam, oil, nitric acid, acetic acid, oxidizing media, urea, etc.
