Ball Valves
These simple, trouble free valves are also designed to operate fully open or fully closed.
Pros
  • Good for throttling clear water
  • Low pressure drops
  • Open and close quickly
  • Simple design and operation
 
Cons
  • Opening too quickly can cause fluid hammer

Generally used for handling large volumes, these valves are very compact.
Pros
  • Can handle large volume
  • Can handle slurries
