Slurry and similar services
Vacuum service
High-pressure and high-temperature water and steam services

Advantages of Butterfly valves

Compact design requires considerably less space, compared to other valves
Light in weight
Quick operation requires less time to open or close
Available in very large sizes
Low-pressure drop and high-pressure recovery

Disadvantages of Butterfly valves

Throttling service is limited to low differential pressure
Cavitation and choked flow are two potential concerns
Disc movement is unguided and affected by flow turbulence
