Lug-style butterfly valves are suitable for end-of-line service but a blind flange is always recommended. Lug-style butterfly valves are manufactured to be compatible with either pneumatic or electric actuation. Disc and seat material should be determined based on application and flow media.

Butterfly valves are usually used purely as shut-off valves for on/off operation. Since the valve disc is in the flow path even when fully open, it is not recommended for use with media containing solids. A full, free passage is therefore not given here. This means that cleaning of the pipeline, e.g. by pigs, is not possible.
Butterfly valves are also suitable to a certain extent for throttling or regulating the flow medium, although they have the following disadvantage due to their design. The further the valve disc is closed, the more the flow velocity increases in the passage. This causes cavitation and water turbulence, which can damage the internal components, especially the seals.
The installation position of the butterfly valve is variable as long as the valve shaft is horizontal.
