Pneumatic butterfly valve drawing
Pneumatic butterfly valve drawing The valve diameter of stainless steel pneumatic butterfly valve is the same as the pipe diameter, which does not affect the flow of medium. The electro pneumatic butterfly valve can be fully opened or closed by 90 degrees, thus saving time. The soft sealing rubber ring can be used in 150 ℃ environment, while the hard sealing of stainless steel pneumatic butterfly valve can be used in 425 ℃ environment.
If it needs to be used in high temperature environment, you can choose to forge or change the material to chrome molybdenum steel, 310S stainless steel, and it can be used at 600 ℃. In case of strict requirements on sealing performance, pneumatic butterfly valves are usually used. In addition to adapting to different media and different temperatures, it can also be used in the environment of impurity media. It is usually used in major petroleum, chemical, paper and shipbuilding industries.
The hard seal pneumatic butterfly valve is manufactured according to the national standard casting and forging standards. The seal is a metal hard seal structure, and the ball is a solid ball after nitriding treatment. The sealing ring surface of the pneumatic butterfly valve of Shanghai Rongjun Valve is welded with cemented carbide, which has the characteristics of high temperature resistance and wear resistance, and is an ideal choice for severe working conditions. Pneumatic butterfly valve is mainly used for steam, heat transfer oil, food, chemical raw materials and other high-temperature medium pipelines.
