Abstract
Sphere valve for low-pressure gas with a pair of annular gaskets outside the PTFE ones, with rectangular sections, placed inside the inlet created by the inside sections' rubber, lactometer angle iron. Both of these are located in the only annular ring, providing the inside and the sealed one with support and centrality in the sphere and perfecting the internal sealed one ensuring that is works even with low pressures.
