How can butterfly valves be installed into a piping system?

Butterfly valves are commonly installed in piping systems using flanged and wafer connections because this method is both effective and practical for ensuring a tight seal and proper alignment within the system.

Flanged connections involve bolting the valve between two flanges on the piping system, which allows for easy installation and removal when maintenance is required. These connections are typically used for larger pipe diameters where secure sealing is crucial.

Wafer connections, on the other hand, are designed to fit between two flanges in a piping system without requiring additional flanges to be bolted. This design makes the installation of butterfly valves more compact and cost-effective, especially in tight spaces. Wafer-style butterfly valves have a central body that fits snugly between the flanges, allowing for quick installation while also maintaining a reliable seal as the valve operates.

Using flanged and wafer connections allows for a simple yet robust installation method, making it the preferred choice for many applications involving butterfly valves in both industrial and commercial settings.
