The American standard ball valve is an American standard valve that uses a ball with a circular passage as the opening and closing member, and the ball rotates with the valve stem to realize the opening and closing action. The opening and closing member of the ball valve is a holed ball that rotates about an axis perpendicular to the passage to achieve the purpose of opening and closing the passage. American standard ball valves are mainly used to open and close pipes and equipment media.
The main casting materials: CF8, CF3, CF8M, CF3M, F51, F53.ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti and other stainless steel castings, Hastelloy, Monel, heat-resistant wear-resistant steel and other special alloy steel castings;
Casting execution standards: GB, JB, HG, American standard API, ANSI, German standard DIN, Japanese standard JIS, British standard BS, etc.;
Casting pressure grade: PN10 ~ PN420, Classl50 ~ class2500;
Casting range: DN15 ~ DN2000, NPS1/2 ~ NPS54 and so on.
The fixed flange ball valve adopts advanced valve seat and American standard ball valve bonnet castings, low friction coefficient, small operating torque, various valve seat materials, wide adaptability, unmistakable handle, flat head valve stem, connection with handle It will not be misplaced, so as to ensure that the switch state indicated by the handle is consistent with the valve. In order to prevent the valve casting switch from being mishandled, there is a locking hole in the fully open and fully closed position of the valve to ensure that the American standard valve is in the correct position. The valve stem is bottom-loaded to prevent pressure from flying out. At the same time, it can form metal contact with the body after the fire to ensure the valve stem is sealed. The spring is arranged between the ball, the American standard ball valve bonnet casting, the valve stem and the valve body. It can generate static electricity from the switching process.
