The ball of the high platform ball valve adopts a plug body that can easily rotate 90 degrees, making it easy to operate and serving as a switch and connecting medium. The ball support methods for high platform ball valves mainly include fixed and floating types. The following will introduce the characteristics of these two ball support methods:
1、 Fixed ball valve: more suitable for high-pressure or large diameter applications; Due to the small torque of the ball and the small deformation of the valve seat, its sealing performance is stable and its service life is long. The ball of a fixed ball valve is connected to the upper and lower valve stems, and the ball can rotate freely along the axis perpendicular to the valve channel, but cannot move along the channel axis.
2、 Floating ball valve: The valve stem is connected to the ball in a movable manner, and the ball has no supporting shaft. The valve seats at both ends of the inlet and outlet of the ball valve are supported, so the ball of the floating ball valve is held flat by the two ends and is in a floating state.
The fixed and floating types of high platform ball valves are widely used in valve products.
