High sensitivity double clap non-return valve. The invention consists of a highly sensitive non-return valve, which is not affected in its operation by gravity, nor does it require elastic elements for its correct operation. For this, it is constituted from a base body (1) in which a control volume (8) is defined, as well as two clappers (4 and 5) located inside the base body (1) for entry and exit. of the fluid, clappers that are mounted on the same axis (6) integral with both clappers and supported at their ends through separate covers (2) and (3) for the base body (1). The clappers (4 and 5) are able to make a turn both clockwise and counterclockwise, to establish the position of fluid inlet towards the control volume (8) with outlet closure, when the pressure in the control volume is less than the outside pressure or to block the inlet to the control volume and allow the outlet to the outside when the pressure in the control volume is greater than the outside pressure.
