Valve for inflatable apparatuses

An inflatable apparatus comprising a valve, and a lumen;

• wherein the valve comprises:
• a housing with a first opening and a second opening, and mounted such that the second opening faces the lumen of said inflatable apparatus;
• a sealing disc adapted for rotating within an inner surface of the housing;
• and 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 body member 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 is able to be lifted away from the body member when pressurized air is applied to the second surface side of the body member, such that air passes through the one or more perforations;
• wherein the sealing disc is configured such that the side edge of the perforated body member releasably engages with the inner surface side of the housing such that passage of air from the first opening and towards the second opening, and vice versa, is directed through the one or more perforations in the body member.
