ROTARY VALVE POSITION INDICATOR |
| 摘要 |
A rotary valve position indicator is disclosed. An example apparatus includes an actuator housing defining an explosion-proof enclosure boundary. An actuator output shaft has a first shaft portion and a second shaft portion. The first shaft portion is partially disposed within the explosion-proof enclosure boundary, and the second shaft portion is disposed outside of the explosion-proof enclosure boundary. A visual position indicator is disposed on the second shaft portion of the actuator output shaft and indicates the rotational position of the actuator output shaft relative to the actuator housing. |
