Abstract: A valve with a valve upper plate defining an inlet, a valve body defining an outlet, and a fluid passage. A closure member is disposed in the fluid passage between the inlet and the outlet and has a convex sealing surface and is rotatable between a closed position in which the closure member extends across the fluid passage with the convex sealing surface oriented towards the inlet and an open position in which fluid is able to flow through the fluid passage from the inlet to the outlet. A resilient sealing ring, when the closure member is in the closed position, is moveable between a first configuration in which the sealing ring forms a seal around a circumference of the convex sealing surface and a second configuration in which the valve comprises a circumferential gap between the convex sealing surface and the sealing ring.
