Abstract
This invention relates to a valve for use in a pipe used for transporting a substance. The valve includes a rotatable disc, a valve seat, and an actuator. The actuator is adapted to rotate the rotatable disc between a closed position, where the rotatable disc is substantially perpendicular to the longitudinal axis of the pipe, and whereby the edges of the rotatable disc are adapted to seal against the valve seat, thus preventing the flow of the substance through the valve, and an open position, wherein the rotatable disc is substantially parallel to the longitudinal axis of the pipe, thus allowing for the flow of the substance through the valve. The valve also includes a protective portion adapted to cover at least a portion of the valve seat during the flow of the substance through the valve, when the valve is open.

15. A valve for use in a pipe used for transporting a substance, said valve including:
-
a) a rotatable disc, b) a valve seat, c) an actuator for rotating the rotatable disc between; i. a closed position, wherein the rotatable disc is substantially perpendicular to the longitudinal axis of the pipe, and whereby the edges of the rotatable disc are adapted to seal against the valve seat, thus preventing the flow of the substance through the valve, and ii. an open position, wherein the rotatable disc is substantially parallel to the longitudinal axis of the pipe, thus allowing the flow of the substance through the valve, d) a movable protective portion fixed substantially at right angles with respect to the rotatable disc, the arrangement and construction being such that the protective portion is adapted to cover at least a portion of the valve seat during the flow of the substance through the valve, when the valve is open. - View Dependent Claims (16, 15, 20, 21, 23, 24, 25, 26, 30, 31, 33, 34)
