Trunnion Ball Valve

Trunnion ball valves are quarter-turn valves used to stop or start the flow of a media in a pipe. The most common type of ball valve has a “free floating” design, so the trunnion type is a design change. Within a trunnion ball valve the ball connects to the stem on one end and on the other end a shaft called the trunnion. Due to this design change, the ball is held firmly in place. In a floating ball valve, the ball is only connected to the stem, and is therefore called floating. This is illustrated in Figure 1 and highlighted by a red box. Trunnion ball valves have many different advantages over free floating valves, they are suitable for low, and high-pressure applications, and offer lower operational costs then free floating ball valves.
