A non-return valve includes a cylindrical valve seat insert that defines a fluid passageway and a valve seat terminating the passageway. A valve closure includes a valve flap that is pivotal about a pivot region with respect to the valve seat between a closed condition in which a periphery of the valve flap operatively engages the valve seat to close the fluid passageway and an open condition in which fluid is permitted to flow through the passageway. A biasing mechanism is interposed between the valve flap and an internal surface of the insert to bias the valve flap into the closed condition, the biasing mechanism being configured and arranged with respect to the valve flap such that a level of bias is adjusted to facilitate movement of the valve flap into the open condition.
