Abstract

A check valve (10) comprises a valve housing (14) defining an opening (16) and a plurality of flapper elements (18) each having a proximal end (26) and a distal end (28), The flapper elements (18) are pivotally mounted to the valve housing (14) at their proximal ends (26) for pivotal movement between a closed position, in which they block the flow of fluid through the opening (16) and an open position in which they permit the flow of fluid through the opening (16). Each flapper element (18) is generally triangular or trapezoidal in shape such that the flapper elements (18) together create a generally conical or frustoconical surface (21) when the valve (10) is in the closed position. A resilient band (36) extending around a circumference of the conical or frustoconical surface (21) defined by the plurality of flapper elements (18) in the closed position for biasing the flapper elements (18) towards the closed position.
