Limit switch boxes that report the open and closed position of quarter-turn valves to the control system. APL 210 for safe areas and APL 510 explosion-proof for hazardous areas, both with a visual dome indicator. They mount on rack-and-pinion actuators through the standard NAMUR bracket, and we make brackets to fit existing valves on board.
