Specification

Floating ball- The floating ball design is the most common type of ball valve. In this type, the ball is not fixed to the stem so a wide range of freedom is available. The upstream pressure helps create the seal by pushing the ball back against the rear or downstream seat.
Trunnion valves- The trunnion ball valve design has a pin securing the ball so it doesn’t dislodge. This design can be used for high velocity systems. Trunnion valves use a special segmented ball. The valve supports the ball with a shaft and the side opposite the shaft using another shaft or post. The shaft can be part of the ball or separate. Trunnion valves provide less friction between the ball and seal.
