Abstract

A butterfly valve member 4 pivotally mounted in a valve casing providing a valve seat has a peripheral sealing ring 6, for engagement with the valve seat, ring 6 being located in an annular groove 7 around the valve member. The sealing ring 6, in axial section, has the form of a 'U' with the base of the 'U' radially outermost and the limbs of the 'U' extending from the base of the 'U' towards the axis of the ring. An incompressible support ring 10 is disposed within the ring 6 between the parts providing the arms of the 'U'. In use the parts of the ring 6 providing the arms of the 'U' normally bear sealingly on the side walls of the groove 7 or on seals provided on these side walls but can be deflected resiliently whereby, in the closed position of the valve, the chamber defined between the ring 6 and groove 7 can be filled with the pressurised fluid upstream of the valve member and the ring 6 thereby expanded resiliently radially outwardly into more effective sealing engagement with the surface 5 of the valve seat formed in the valve casing. <IMAGE>
