High pressure ball valve refers to the valve driven by the stem open and close components (ball), with the stem axis as the center of rotation movement.Used for hydraulic machinery equipment, hydraulic switch, natural gas and so on, high-pressure ball valves published in the 1950s, with the rapid development of science and technology, production technology and product structure of continuous improvement, in a short span of 40 years, the rapid development of the main valve.Most domestic ball valve manufacturers are based on this standard design production of hydraulic capsule accumulator wholesale,.

However, this standard is perfect and has no specification. The nominal diameter of the floating ball valve is DN1200 and the nominal diameter of the fixed ball valve is DN2000.According to the valve specification and data of the factory, the nominal size of the floating ball valve is DN6, and the nominal size of the fixed ball valve is DN50.After the research, the connection size of the manufacturers can not be unified, in order to have a unified standard, the user can be compatible with the same specifications in the selection and installation, stainless steel capsule accumulator wholesale recommended by the national general machinery research institute to modify GB/ t12221-2005.Design institute and user suggested standard selection, ball valve manufacturers according to the standard design and manufacturing.
