1、 The application scope of internal thread pneumatic ball valve The internal thread pneumatic ball valve and butt welding pneumatic ball valve are applicable to various pipelines with PN1.0~4.0MPa, operating temperature of - 29~180 ℃ (the sealing ring is reinforced polytetrafluoroethylene) or - 29~300 ℃ (the sealing ring is aligned polystyrene), and are used to cut off or connect the medium in the pipeline. Different materials can be used for water, steam, oil, nitric acid, acetic acid and other media.

Characteristics of pneumatic butterfly valve
1. Since the main parts of the pneumatic butterfly valve are made of austenitic stainless steel, the excellent temperature resistance and corrosion resistance of the hose are guaranteed. The operating temperature range of the hose is extremely wide, ranging from - 196 to 600 degrees. The applicable stainless steel brand is selected for the applied hose according to the corrosivity of the medium through which the pipe passes to ensure the corrosion resistance of the hose.
2. The pneumatic butterfly valve is made of 1Cr18Ni9Ti stainless steel, which has strong corrosion resistance ability.
3. The pipe body of pneumatic butterfly valve is a thin-walled stainless steel pipe formed hydraulically, which has strong flexibility, flexibility, bending and anti vibration ability, and enhanced maintenance of woven mesh sleeve, so that it has higher pressure bearing ability.
4. The connection of the two ends of the pneumatic butterfly valve can also be made into other connection modes besides the thread and flange standards, which is convenient for connection and application.
5. Pneumatic butterfly valve is not only suitable for matching with rotary joint, but also widely used for soft connection of various fluid media.
