- 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
