1. Fluid resistance pneumatic ball valve is one of the smallest fluid resistance in all valve categories. Even the reduced diameter pneumatic ball valve has relatively low fluid resistance.
2. The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate stably and flexibly for a long time.
3. The sealing performance of the valve seat is good. The sealing ring made of elastic materials such as polytetrafluoroethylene is easy to seal, and the sealing capacity of the pneumatic ball valve increases with the increase of the medium pressure.
4. The valve rod seal is reliable. Because the valve rod only operates as if it is rotating rather than lifting, the packing seal of the valve rod is not easy to be damaged, and the sealing capacity increases with the increase of the pressure of the medium
5. Since materials such as polytetrafluoroethylene have good self-lubricating property and small friction loss with the ball, the service life of pneumatic ball valve is long.
6. Anti static function: set a spring between the ball, valve stem and valve body, which can lead out the static electricity generated during the switching process.
7. The lower mounted valve stem and the convex step at the head of the valve stem prevent the valve stem from ejecting. If the valve stem seal is damaged due to fire, metal contact can also be formed between the convex step and the valve body to ensure the valve stem sealing.

Pressure range of stainless steel pneumatic butterfly valve
Stainless steel pneumatic butterfly valve is an important part in modern industry. Stainless steel pneumatic butterfly valve is used as wire and cable maintenance pipe and civil shower hose for wires, cables, automatic instrument signals, with specifications ranging from 3mm to 150mm.
Product characteristics:
1. Wide temperature resistance characteristics - temperature range of pneumatic butterfly valve application: - 196 ℃ -+450 ℃ 2. Good corrosion resistance - due to the use of stainless steel materials, the hose can resist the corrosion of most salt and alkali organics, and has quite good corrosion resistance to most acids.
3. Excellent weather resistance - no aging and deterioration after long-term use.
4. Extremely high pressure resistance? The hose with a diameter of 10mm can accept a pressure of 20Mpa; The hose with a diameter of 300mm can also accept a pressure of 1Mpa.
5. Ultra long service life - 1Mpa pressure, regular dynamic bending radius, fatigue life up to 3000 times; The fatigue life will increase with the increase of dynamic bending radius. Pressure range of stainless steel pneumatic butterfly valve:
The pneumatic butterfly valve is the main pressure bearing part of the hose device in the pressure pipeline, and also acts as a sheath for the bellows. According to the pressure in the pipeline and the application site, one or more layers of stainless steel wires or steel strips can be selected to stop weaving. The pressure range of the hose is generally PN0.6 - 32.0Mpa. The maximum is 42.0Mpa Pneumatic butterfly valve products include oil conveying and suction hose, steam hose, sand blasting hose, acid and alkali conveying and suction hose, food hose, oxygen blowing hose and various special-shaped hose, which are widely used in machinery, chemical industry, petroleum, metallurgy, food and other industries
