A butterfly valve includes a valve housing 12 defining a conduit 14 through which fluid can flow. A valve plate 16 is located in the conduit 14 and is rotatable between a closed position in which the valve plate prevents the flow of fluid through the conduit and an open position in which the valve plate permits the flow of fluid through the conduit. In the closed position, the valve plate 16 is tilted with respect to the conduit 14. This provides improved valve initial opening/closing response. |
