用途與性能規(guī)范Application and Performance Criterion

1．球閥廣泛適用于食品、環(huán)保、冶金、石油化工等管路系統(tǒng)中。具有調(diào)節(jié)管路流量及截流等功能。

2．該閥根據(jù)閥體、密封材料的不同可適用于工作溫度- 30一380℃的蒸汽、石油或一般腐蝕性流體介質(zhì)管路上．作為控制介質(zhì)的啟閉機(jī)構(gòu)。

1.Ball valve is widely applied in the piping systems offood, environmental protection, metallurgy, petrochemical

industry, etc, and has the function of adjusting or stopping the flow in the pipeline.

2.According to the differences of valve body and sealing material, this valve can be used in the pipeline for supplying steam, petroleum,general corrosive fluid or other medium at working temperature between 30 and 380t.
