1. Wear resistance When the fluid medium is a suspension containing high concentration of abrasive particles, the internal material of the valve should be hard.
2. The shape and structure of the valve core are mainly considered according to the selected flow characteristics, unbalanced force and other factors.
3. Medium temperature and pressure When the temperature and pressure of the medium are high and vary greatly, the valve core and valve seat materials shall be selected with little change in temperature and pressure.
4. Prevent flashing and cavitation flashing and cavitation only occur in liquid medium. In the actual production process, flashing and cavitation will generate vibration and noise, which will shorten the service life of the valve. Therefore, flashing and cavitation of the valve should be prevented when selecting the valve.
5. Corrosion resistance As the medium is corrosive, try to select valves with simple structure.

In fact, many companies know exactly how critical product quality is. Of course, the same is true for pneumatic butterfly valves. How do we improve the overall product quality. Of course, this aspect must be done from scientific research, design, raw materials, production and processing, and final inspection. Each of these links has a great relationship. Only when we do a good job in these links can we finally ensure the improvement of quality. It is best for you to really understand the actual situation from your own perspective and determine how you want to do it.
