The body has a first beam (2a) located in the passageway transversely to the direction of the air flow through said passageway at the outer end and a transverse flexible membrane (7) located within the passageway on the outer surface of said beam (2a). The valve further comprises a cap (4) securable to the outer end (1b) of the valve having an opening with a size largely corresponding to the inner size of the passageway. The opening is defined by a circumferential rim (14). The cap is provided with a second beam (2b) located in parallel along said first beam (2a) and the membrane (7) is held between said first beam (2a) and said second beam (2b). The first beam (2a) and the second beam (2b) are provided with secu
