A valve comprising a valve body having a flow passage therethrough, a gate element having an orifice, and actuation means operable to move the gate element, wherein the gate element is supported for rotation by a first recess within the valve body and the valve body defines a pressure-containing housing around the gate element,Gate Valves wherein further the actuation means comprise a drive element rotatably supported by a second recess of the valve body, a compensator wheel rotatably supported by a recess associated with the gate element, the drive element and compensator wheel being linked such that rotational movement of the drive element is transferred into rotational movement of the gate element by the compensator wheel, and wherein the drive element is provided with an eccentric pin and the compensator wheel is provided with an eccentric hole.
