The ball valve is a universal device that features a spherical closure that provides control of the flow of gas or liquid. The ball valve is made up of a bore which is responsible for opening and closing the valve for the liquid to flow. There are different styles of ball valves but for homebrewing, the most popular type is the fully welded which provides a smooth finish on the brew pot.
The ball valve works as a faucet in any homebrewing system. Seasoned home brewers often rely on ball valves to make the process of brewing beer easier. This is the reason why ball valves are installed in brew pots or other brewing equipment for the easy transfer of the liquid.
While the main function of the ball valve is to ensure a steady flow of liquid without the risk of leaking, it also serves other functions. One of the underrated function of a ball valve is that it provides effective drainage on the brew pot without causing too much agitation on the liquid thus the liquid can easily drain without bringing in too much debris.
When brewing beer, homebrewers often handle large volumes of liquid thus picking up the kettle and pouring the wort into the fermenter can be a difficult feat. With the ball valve, this back-breaking task is avoided. A ball valve can also be installed to a counterflow chiller so that the wort can easily be transferred.
