A ball valve is a universal device that provides control over the flow of gas or liquid. Most ball valves are 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, and in this section of our website, we feature brass and stainless steel ball valves for liquid and accessories. The most popular type for homebrewing is the fully welded ball valve, which provides a smooth finish on the brew pot.
The ball valve works basically as a faucet in a home brewing system. Seasoned home brewers often rely on stainless steel ball valves to make the process of transferring liquid from one vessel to another much easier and more sanitary.
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 functions 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.
Depending on where and how you plan to use the ball valve you can purchase 1, 2 or 3 piece ball valves, Tri-Clover, pull or squeeze trigger valves, or if space is limited, even mini stainless steel ball valves.
