O-type soft seal ball valve
O-type soft seal cut-off ball valve (hereinafter referred to as cut-off ball valve) is a rotary control valve. The spherical surface is specially hardened to make its surface smooth and wear-resistant. The product has the advantages of exquisite and reasonable structure, large flow capacity, high allowable differential pressure, good sealing performance, and strong interchangeability of parts. Therefore, it is widely used to cut off or open the medium in gas, liquid, slurry and other transmission pipelines in petroleum, chemical, pharmaceutical, metallurgy, light textile, papermaking, sewage treatment and other departments, so that the production process can be carried out according to a certain procedure.
