The functions of stainless steel floating pneumatic ball valve and plastic floating pneumatic ball valve are almost the same, but the price of stainless steel floating pneumatic ball valve is much higher than that of plastic floating pneumatic ball valve. The price of the small hole floating pneumatic ball valve is proportional to its advantages. The most expensive one is up to 800 yuan, and the cheapest one is 35 yuan.

Selection of pneumatic butterfly valve products
1. Fluids containing acid (* 1) and chloride ions shall not be used. Otherwise, corrosion may occur in a very short time
2. It is not suitable for corrosive gas and environment close to the sea. Products with special chlorine prevention measures can be selected
3. Please confirm the applicable laws and regulations. In terms of applicable laws and regulations, please pay attention to selecting products that are suitable for fire protection, tap water and other regulations
4. Please confirm the application pressure. If the allowable pressure is exceeded during operation, the pipe body may be damaged
5. Please confirm the operating temperature. The compressive strength of the tube body is different under different operating temperatures
6. Please confirm the purpose of application. Measures such as center alignment, shockproof and anti foundation settlement of separated piping shall be taken to select products in a targeted manner. If you don't understand, please communicate with our technical personnel!
7. Please confirm the total length or allowable displacement of the pneumatic butterfly valve pipe body. The service life of the tube body will be reduced when the position beyond the allowable displacement is used. Please select the appropriate length.
1) As for acids, their corrosion resistance is different according to different types of acids, so please contact our factory for technical communication
2) Fluoroelastomer lining can also be supplied under high acid and alkali corrosion
