What are the characteristics of pneumatic butterfly valve??
With the rapid development of modern transportation industry, there are more and more people with cars. It is these transportation tools that make our travel very convenient and do not need to travel as long as before. Of course, the use of pneumatic butterfly valves matched with road vehicles such as automobiles and motorcycles is very common!
When all kinds of transportation vehicles are driving on the road, they will always encounter bumpy air. Although they used to have springs to prevent the uneven air from bringing stability to passengers, the spring will produce a rebound movement after it is stopped, so the existence of the spring will only delay the vibration time, losing its original reason for existence. The pneumatic butterfly valve can just stop the rebound movement of the spring, so that the car can run smoothly. We found that the shock absorption effect of each car is different. Generally speaking, the shock absorption effect of European and American cars is relatively good. Because of its chassis weight, the corresponding pneumatic butterfly valve will also be relatively hard, which can prevent the spring rebound to a greater extent. If you choose a pneumatic butterfly valve with a soft texture, you will not be able to prevent the spring rebound. So, We should select a suitable pneumatic butterfly valve according to the rebound strength of the spring.

How to select pneumatic butterfly valve
If you want to purchase a good pneumatic butterfly valve, you should consider the comprehensive elements of the pneumatic butterfly valve, the medium characteristics of the pneumatic butterfly valve, the operating conditions and the natural conditions of his device site, as well as the size of the pipe diameter of the pneumatic butterfly valve, the maximum displacement and other factors.
The flexible body of pneumatic butterfly valve is divided into annular bellows flexible body and spiral bellows flexible body. In order to compensate displacement, device deflection and foundation settlement, absorb vibration and reduce noise, it is advisable to select annular bellows pneumatic butterfly valve; For places with high pressure but infrequent displacement and vibration, spiral bellows pneumatic butterfly valve should be selected.
