the opening and closing piece ball and stem casting (forging) as a whole, to prevent pressure changes due to pressure caused by pieces of the stem out the possibility of a fundamental guarantee for the project in the use of safety;
4, compact structure, the smallest body cavity space, reducing the retention of the medium, the other, a special molding process, so that good sealing surface density, coupled with the word combination of the ring PTFE packing, the valve to achieve zero leakage;
5, two-piece, three-piece structure can adapt to different requirements of the pipeline system and working conditions, including three ball to allow separation of the main body and both sides of the body can achieve fast online replacement and maintenance.
Ball valve has an exceptionally strong chlorine corrosion resistance, suitable temperature conditions in the -20-150 ℃, long-term transport any concentration of acid, alkali, salt liquid medium. Long service life, aging, toxin-free advantages of both the strength of carbon steel shell, but also corrosion-resistant materials in lined, oil, chemicals, rubber, plastics, pharmaceuticals, paper making, electroplating, metallurgy, etc. Ideal for many industries. Scope: Urban, chemical, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection.
