Valve for inflatable apparatuses

A valve for inflatable apparatuses comprising:

• i) a housing with a first opening and a second opening, and adapted for being mounted to an inflatable apparatus such that the second opening faces the lumen of said inflatable apparatus;
• ii) a sealing disc adapted for rotating within the housing;
• and
• iii) a handle coupled to the sealing disc, and adapted for rotating the sealing disc;
• wherein the sealing disc comprises:
• a) a perforated body member with opposed first and second surface sides, and a side edge, and wherein one or more perforations extend through the sealing disc from the first surface side to the second surface side;
• and
• b) a cover plate adapted for covering the one or more perforations in the body member on the first surface side;
• wherein at least a part of the cover plate may be lifted away from the body member when pressurized air is applied to the second surface side of the body member, such that air may pass through the one or more perforations;
• wherein the sealing disc is configured such that the side edge can releasably engage with the inner surface side of the housing such that air passage from the first opening and towards the second opening, or vice versa, is directed through the one or more perforations in the body member.
