Product description
The stainless steel floating ball valve has the action of rotating 90 degrees. The cock body is a sphere with a circular through hole or channel passing through its axis. The stainless steel ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small torque can be closed tightly. The stainless steel floating ball valve is most suitable for use as a switch and shut-off valve. The stainless steel flanged ball valve is made of polytetrafluoroethylene, p-polyphenyl and other polymer materials, which have good sealing performance, but the material is relatively soft. Because the material is softer, but must reach a certain sealing pressure, it is bound to increase the opening and closing torque. Stainless steel valves are suitable for water, steam, oil, nitric acid, acetic acid, oxidizing media, urea and other media.
