ZSHOY series “O” type hard seal ball valve adopts metal hard seal structure. The ball core adopts full diameter, large rated flow coefficient and small flow resistance. The ball core and seat surface are spray-welded with carbide and have extremely strong wear resistance. The valve body adopts two-piece or three-piece structure design with simple structure; the valve seat limit structure design maintains the stability of the torque; the bottom-mounted valve stem prevents flying out of the design; and the floating or fixed ball structure is selected according to different media working conditions. Widely used in petroleum, chemical, metallurgy, papermaking, etc. for the cutting or opening of gases, liquids, slurries and other media.
