Abstract
A device for controlling the flow of a fluid through a conduit from an upstream side of the device to a downstream side of the device. The device includes a housing defining a valve aperture and a mounting member arranged on the downstream side of the valve aperture. A valve member is movably mounted on the mounting member and is arranged to selectively open and close the valve aperture to control the flow of fluid. A soft seal is arranged on the housing for substantially sealing the valve aperture when the valve member contacts the housing. The soft seal is located downstream of a convex curved surface of the housing which is shaped to separate the flow of fluid through the valve aperture away from the surface of the housing such that the fluid does not impinge directly on the soft seal.
