The existing advanced pneumatic butterfly valve is a three eccentric metal hard seal pneumatic butterfly valve. The valve body and valve seat are integral components, and the sealing surface of the valve seat is welded with heat-resistant and corrosion-resistant alloy materials. This pneumatic butterfly valve is more resistant to high temperature than the general pneumatic butterfly valve.

Why pneumatic butterfly valve will gradually replace rubber hose
In the past, pneumatic butterfly valves almost swept over the industry originally belonging to rubber pipes. More and more people are familiar with the advantages of pneumatic butterfly valves. With the maturity of pneumatic butterfly valve technology, more and more industries have used pneumatic butterfly valves to replace rubber pipes. What is the difference between the two? Which elements lead to the gradual replacement of rubber pipe by pneumatic butterfly valve? The following is a short compilation to analyze for you:
1. Weight:
Each rubber tube weighs nearly 100 kg, and four people are required to lift it during installation. The pneumatic butterfly valve is made of thin-walled pipes, so it is light, only 20-30 kg, and only two people are needed for installation.
2. Efficiency:
It takes 14 hours to unload a ship of crude oil (300 tons for rowing) with rubber tubes due to low temperature, low pressure and other reasons, and only 95% of the crude oil can be extracted from each ship. The residual oil cannot be discharged and must be returned with the ship. The pumping efficiency of pneumatic butterfly valve can reach 98.3%, which only takes 10 hours.
3. Life:
The service life of rubber pipe is only ten days to several months, while the service life of pneumatic butterfly valve can reach three to five years. In addition, the leakage of small area can also be repaired and reused after repair.
4. Safety:
Blasting accidents often occur when rubber pipes are used. The blasting gap not only forms crude oil spurting everywhere, but also may hurt people. The application reliability of pneumatic butterfly valve is much higher than it, and it is impossible to produce such results.
To sum up, compared with the rubber pipe, the pneumatic butterfly valve has many advantages such as convenient, safe, reliable, high efficiency, long service life and so on. Therefore, the pneumatic butterfly valve is capable of replacing the rubber pipe. Aoguang can also guess that the application scope of pneumatic butterfly valve will be further expanded, with an infinite way out.
