One or more techniques and/or systems are disclosed for a flow control valve element, which may comprise a generally spherical shape. An inlet and outlet are formed in the element, with a fluid passage disposed between. The respective inlet and outlet are defined by a lip, and at least the outlet has a lip face comprising a width less than that of an adjacent element wall thickness. The element can comprise a pair of opposing flats formed in the wall, where the flats respectively comprise an external flat portion of the element wall and an opposing internal flat portion of the element wall.
