Abstract
A modular valve position indicator which interfaces with a valve, actuator and other auxiliary equipment meeting NAMUR standards is described. The position of the valve within the flow circuit is indicated by at least one of an LED display and color coded indicia. A drum having the color coded indicia thereon, rotates through a window defined by members of the indicator in response to the rotation of the valve.
