Q:The difference between vertical and horizontal butterfly valves in municipal water supply
Vertical and horizontal only installation directions and installation methods are different. Functionally, there is no difference.The main difference between the two methods of installation is that:1. horizontal can effectively avoid the high temperature radiation above the pipe. The disadvantage is that it takes up a lot of space.The advantage of the 2. vertical is that the occupation space is smaller, and it is easy to install. If the pipeline is higher, it is not convenient for maintenance.
