Fully Welded Ball Valve

The seat of the fully welded ball valve is composed 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. Since the valve body 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.
