Abstract

A check valve (10) comprises a valve housing (2) defining an opening (6). A valve housing sealing surface (16) surrounds the opening (6). The valve further comprises a plurality of flapper elements (8). Each flapper element (8) is pivotally mounted to the valve housing (4) about a respective axis (10) transverse to the opening (6) for rotation between an open position in which the flapper elements (8) permit flow of fluid through the opening (6) and a closed position in which they block the flow of fluid through the opening (6). Each flapper element (8) comprises a first side (28) facing the valve housing sealing surface (16) in the closed position, a second side (30), opposed to the first side (28) and facing away from the valve housing sealing surface (16) in the closed position, a base end (32), the flapper element (8) being mounted to the valve housing (4) at its base end (32), a first edge region (34a) extending away from the base end (32) for sealing engagement with the valve housing sealing surface (16) in the closed position of the flapper element (8) and a second edge region (36a) extending away from the base end (32) for sealing engagement with the base end (32) of an adjacent flapper element (8) in the closed position of the flapper element (8). An edge (36) of the second edge region (36a) of the flapper element (8) engages with the second side (30) of an adjacent flapper element (8) when the flapper elements (8) are in the open position.
