The N-Series valve position indicators are mounted on a printed circuit board which, in turn, is located in a preformed slot in the top housing of the valve. It is
held in place by the label on top of the valve. This label must be removed in order to access the position indicator circuit board. As such, the position indicator
replacement or add-on kit includes a spare label to be used, since the original adhesive likely will not be adequate to be used a second time.
The position indicator kit can be ordered under part number N-O-K.
Position indicator kit includes the circuit board, connection cable and top label.
