Fetures of Floating Ball Valves

The main feature of a floating ball valve is that the ball is not held in a trunnion, instead, it  is only supported by the inlet and outlet valve seats. The ball and the stem actively linked, thus allow the ball to “float”. The Ball can rotate freely between the two seats when driven by the handle or other actuators. When the hole of the ball aligns with the channel, the ball valve is opens and fluid flows through it. At this moment, valve resistance is minimal. When the ball rotates 90 degrees, the hole of the ball becomes perpendicular to the channel. At this point, the ball valve closes and is pushed against the oulet seat by media pressure, ensuring a tight seal.
