There are many types of pneumatic butterfly valves, the most commonly used ones are wafer pneumatic butterfly valves and flange pneumatic butterfly valves. Among these two, wafer pneumatic butterfly valves are more commonly used. The pneumatic butterfly valve we want to replace should pay attention to the following points:
1. First look at the diameter, and check the thickness of the valve according to the diameter. This thickness refers to the distance between the two flanges. If there is no problem after checking, each There will be some differences in the thickness of the valves from the manufacturer. Thin ones can be replaced, but thick ones cannot. In that case, we have to negotiate specifically based on the site;
2. After looking at the actual medium, temperature, pressure, etc. used at the customer’s site, we will determine the actual use at the customer’s site. We can also provide customers with professional opinions and suggestions on the life and maintenance of the valve.
3. If the above two points are met, then the pneumatic butterfly valve can be replaced.
