A roll over vent valve comprising: a housing (1) having a fluid inlet and a fluid outlet, the latter comprising a substantially elongated slit-like outlet aperture (6) of the housing bounded by a valve seating (5a). There is furthermore provided a float member (15) located in the housing and axially displaceable within the housing between the inlet and the outlet; an elongated flexible closure membrane strip (23) anchored at one end thereof to an end of the float member adjacent the outlet and at a portion thereof offset with respect to the outlet; spring biassing means (27) located within the housing and bearing on the float member so as to spring bias it in the direction of the outlet; whereby the spring biassing together with buoyancy forces acting on the float member tend to press the membrane strip into sealing engagement with the outlet aperture whilst gravity forces acting on the float member tend to displace the float member away from the outlet so as to progressively detach the strip from sealing engagement with the outlet.
