A control element (54) for a rotary control valve is attached to a rotating shaft (56) by at least one ear (76). The control element includes at least two surfaces, the first surface (60) being generally sealable with a flow ring (64). The second surface (62) is generally recessed from the first surface to facilitate fluid flowing through the valve across the first surface to prevent scaling or buildup of foreign material on that surface.

L'élément de contrôle comprend au moins deux surfaces, la première surface (60) pouvant être généralement scellée par une bague d'écoulement (64). La seconde surface (62) est généralement évidée à partir de la première surface afin de faciliter l'écoulement du fluide par la vanne dans la première surface afin de prévenir l'entartrage ou la formation d'une matière étrangère sur cette surface.
