Rotary ball valve combines the advantages of butterfly valve, ball valve, and eccentric rotary valve, adopting the design of offset shaft and eccentric butterfly valve. At the same time, combined with the design of arc spherical surface of the valve core, the valve core quickly detaches from the sealing seat when opened to reduce the friction of the sealing surface. The valve core has better sealing performance when closed. This series of products solves the problem of single linear and single eccentric butterfly valves where the valve plate cannot detach from the sealing surface after opening, achieving extended service life and possessing the structural advantages of small volume and light weight of butterfly valves. Scope of application: petroleum, chemical industry, metallurgy, electricity, heating, etc.
