In some embodiments, a rotary shaft position indicating and display apparatus for use with a device having a rotatable shaft may include one or more of the following features: (a) a housing having a base with a cover secured to said base and defining a hollow sealed chamber, (b) an actuator shaft journaled for rotation in said base and extending through said base into said sealed chamber, (c) at least one electromechanical actuating element mounted on said actuator shaft, (d) a frusto-conical member having graphics information representative of said actuator shaft position viewable through a window area, (e) said cover having a frusto-conical base, (f) female threads on the interior of the frusto-conical base, and (g) male threads on the base housing to accept the female threads on the interior of the frusto-conical base.

Rotatable shaft position indicator

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.
