Trunnion mounted ball valve body material: WCB, WC6, WC9, CF8, CF8M, CF3, CF3M, etc. The trunnion mounted American standard ball valve usually uses rubber, nylon and Teflon as the seat seal material, so its use temperature is affected by the valve seat.

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 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.

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.

Floating ball valves are used primarily in the pipeline to cut, distribute and change the direction of flow of the medium. Floating ball valve is a new type of valve widely used in recent years.

There are many types of ball valves, and floating ball valve is one of them. Like other valves, the floating ball valve has the advantages of reliable valve stem sealing and a wide range of applications.

The floating ball valve is small in size, light in weight and simple in structure. The ball of the floating ball valve has a free floating function, which can better ensure the sealing; the ball can be freely rotated in the seat sealing ring by means of the valve stem.

Ball valve can be divided into many kinds, its class pressure can be 150,300 and 600. Its body can be made of Alloy 20, ductile iron. bronze, aluminum and carbon steel. For its seat, the material can be carbon graphite, fire seal, and RTFE.Ball valve parts is constituted by many components.
