Ball valve is mainly used in connecting or blocking line medium, especially in the pleading agile open closed parts, such as emergency relief. Because the ball valve has a brief layout, less parts, light weight, good sealing performance advantages.

The ball may cause internal leakage,this may happened because of many reasons,so it's necessary to check and find the reasons and solve it immediately,now we check and following methods.The reason for the internal leakage of the industrial ball valve

There are some methods to check ball valve if it’s inner leakage and process to handle the leakage,and daily maintenance methods for ball valve.

The ball valve is one of many fluid control valves. The opening and closing member is a circular spherical body with a hole, and the ball is rotated back and forth around the axis of the rod by 0-90° to achieve the purpose of opening or closing the flow.

The ball valve is mainly used to cut off the flow, distribute the flow rate and change the flow direction. It can rotate at 90 degrees. Ball valves have many functions, and they can also be used as switches.

Ball valve, the opening and closing part(sphere) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control.

The fully welded ball valve seat is made up of a carbonized Teflon seal ring and a disc spring, so it is adaptable to changes in pressure and temperature, and does not cause any slippage within the marked pressure and temperature range.

The ball of the floating ball valve is floating without a mounted shaft. Under the action of the medium pressure, the ball can generate a certain displacement and press on the sealing ring at the outlet end to ensure the sealing of the outlet end, which is a single-sided forced seal.

Floating ball valves are mainly used to cut off or turn on the medium, and can also be used for fluid regulation and control. The ball of the floating ball valve has only the upper valve stem, and the ball can be slightly displaced, so it is called a floating ball valve.

The floating ball valve has a motion of 90° of rotation, the body of the plug is a sphere, with a circular through hole or passage through its axis. The ball valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium.
