Product Description
The two-piece floating forged steel ball valve has a long service life because the sealing ring materials such as polytetrafluoroethylene have good self lubrication and small friction loss with the ball. The floating forged steel ball valve has compact structure, reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are often closed, which is not easy to be eroded by the medium. It is easy to operate and maintain. It is suitable for: chemical industry, petroleum, natural gas, metallurgy and other industries, as well as long-distance natural gas transmission pipelines containing hydrogen sulfide medium, many impurities and serious corrosion.
