Information You Should Have About Trunnion Ball Valve Design and Its Work
The trunnion ball valve is a quarter-turn valve that is used to stop or start the flow of media in a pipe. The most common type of ball valve has a “free-floating” design, which is why it is a design change. Within this device, the ball connects to the stem on one end, and on the other end, a shaft called the trunnion. Because of this design change, the ball is held firmly in place. For high-pressure applications, it is an ideal Trunnion Ball Valve Design type. In this device, the ball has some freedom of movement. During use, the ball floats slightly downstream against the seat ring and creates a sealing only on one side of the device. Apart from this, the torque on the stem is always increased. This is the point when its design provides a solution. In the trunnion valve design, the ball is not floating as it is connected to this. It is beneficial since it will maintain a proper seal on both sides, and there is no added torque to the steam. Thus, for higher pressure applic...
