Here’s why homebrewers like to use butterfly valves:

Regular ball valves can trap wort inside of them. If the wort doesn’t get completely cleaned out it can become infected & turn sour, transmitting that infection to the next wort to travel through the valve.  A favorite of homebrewers, sanitary butterfly valves are easily cleaned in place. Because their internal mechanism is not complex, they can also easily be taken apart for a deeper cleaning when desired.
