The main characteristic of this full welded ball valve is that since the seat is made of a carbonized Teflon seal ring and a disc spring, it is highly adaptable to changes in pressure and temperature, and does not cause any slippage in the marked pressure and temperature range. The valve body is welded from a steel pipe. Since its material is the same as the pipe material, there will be no uneven stress, and it will not be deformed due to earthquakes and vehicles passing through the ground. The pipe is resistant to aging. The length of the valve body and the height of the valve stem can be adjusted according to the construction and design requirements of the pipeline. The valve stem is explosion-proof.
It is suitable for all kinds of fluid pipes, heat treatment pipes and industrial gas and heat pipes. It is widely used in all fields. Its superior quality and high performance stability are beyond ordinary cast steel ball valves. Its service life of is much longer than that of cast steel ball valves.
