Abstract
A valve has a moveable member movable between open and closed configurations and a cutting device arranged to shear against an anvil member when moving between the open and closed configurations and a sealing member providing a seat for seating of the moveable member when the moveable member is in the closed configuration. The anvil member and the sealing member are moveable relative to one another when the moveable member is moving from the open to the closed configuration. During opening and closing the sealing member is displaced away from the cutting device as the cutting device engages the anvil member. The sealing member is pushed away from the moveable member and the anvil to a maximum separation from the movable member at the point on the stroke when the cutting surface of the moveable member is moving past the anvil member.
