Abstract

The disclosure relates to a valve assembly (2) comprising a valve body (4) comprising a first port (6), a second port (8) and a fluid passageway (10) extending therebetween. A valve member (12), comprising a through port (14), is arranged in the fluid passageway (10) and is moveable between an open position and a closed position. A sealing arrangement (15A) is arranged between the first port (6) and the valve member (12) and comprises a sealing member (16) arranged to seal against the valve member (12) such that fluid cannot flow around an outer surface (34) of the valve member (12). The sealing arrangement further comprises a sleeve (18) arranged in the fluid passageway (10) between the first port (6) and the valve member (12); and a deformable, incompressible, medium (20) contained around the sleeve (18) and arranged such that, in use, a fluid within the sleeve (18) exerts an outward pressure on the sleeve (18) causing the sleeve (18) to deform and act on the medium (20) which applies a force to push the sealing member (16) against the valve member (12).
