VALVES FOR THE OBTURATION AND REGULATION OF CORROSIVE FLUIDS, characterized by being of a straight type, achieving the regulation or sealing of the passage of fluid from one tube to the other, bringing the flexible membrane more or less close to the separation wall of said tubules. At the same time, the same, membrane separates in an absolute way the cavity through which the fluid circulates, from the cavity in which the mechanism is housed. This ensures that the only parts in contact with the corrosive fluids are the tubular body and the membrane or diaphragm. The corrosive action of the external environment is avoided on the basis that the threaded spindle that moves the membrane never goes outside.
