Installation requirements for DN500 butterfly valve
Thread Content
The current company project involves the installation of 2 DN500 butterfly valves; given that the flow direction of the liquid is correct, should they be installed horizontally or vertically? ? ? ?

But for tees, especially with gases, when using tees it is sometimes necessary to consider preventing condensation, as well as the corrosion that can result from condensation, and blockages caused by the deposition or solidification of substances. For liquids, it is necessary to prevent blockages caused by solidification or the settlement of impurities.
Horizontal should be better than vertical for such a large pipe diameter
Depending on your installation height, install it vertically if it facilitates operation
Do you mean the valve body is horizontal, or the valve shaft is horizontal?
Butterfly valves also have specific installation requirements; not all installation angles are permitted. The recommended installation method for the wafer butterfly valve in our company is to install the valve stem at an angle of 45° to 90°. Horizontal installation will lead to increased wear of the packing seal, resulting in leaks. It is recommended to carefully read the valve’s instruction manual.
How to install it depends on the layout of the pipes; valves cannot be installed outside the system
