An analog value adjustment circuit includes a fuse circuit that outputs fuse data whose value changes corresponding to whether first through Nth fuse elements are in a cutting state, or in a non-cutting state and an analog value output circuit that receives the fuse data from the fuse circuit, and outputs an analog value that is adjusted in a given adjustment range corresponding to the fuse data. The cover includes a number of inter-engageable cover sections, each exhibiting a lightweight plasticized construction and extending in both widthwise and lengthwise fashion relative to an upper lip edge defining an open perimeter of the barge. At least one circular motion inducement feature is positioned in a portion of the valve body, the seat ring assembly, or both.
