Description and analysis of manual floating ball valve

Manual ball valve, butterfly valve and plug valve are the same type of valve. The difference is that the closing part of the ball valve is a ball, which rotates around the center line of the valve body to achieve opening and closing. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. The three-piece ball valve is a new type of valve that has been widely used in recent years. This type of valve should generally be installed horizontally in the pipeline.

Floating Ball Valve

NSW valve company manual floating ball valve seat has good sealing performance. The sealing ring of the ball valve is mostly made of elastic materials such as PTFE (RPTFE, NYLON, DEVLON, PEEK etc. ). The soft sealing structure is easy to ensure the sealing, and as the medium pressure increases, the sealing force of the ball valve increases. The stem seal is reliable. When the ball valve is opened and closed, the valve stem only rotates and does not move up and down. The valve stem packing seal is not easy to be damaged. The sealing force of the valve stem reverse seal increases with the increase of medium pressure. Because PTFE and other materials have good self-lubricating properties, friction damage with the ball valve ball is small, and the ball valve has a long service life. The utility model can be equipped with pneumatic, electric, hydraulic and other driving mechanisms to realize remote control and automatic operation. The ball valve channel is smooth and can transport viscous fluids, slurries and solid particles.

Manual floating ball valve is a kind of valve that came out in the 1950s. In half a century, the ball valve has developed into a major valve category. The ball valve is mainly used to cut off or connect the medium, and can also be used for fluid adjustment and control. The Segment ball valve (V notch ball valve) can perform more accurate flow adjustment and control, and the three-way ball valve is used to distribute the medium and change the flow direction of the medium. Manual ball valves are named mainly based on the driving mode of the ball valve by turning the hand wheel or handle.
