Hybrid Manual and Hydraulic Actuator Override |
| 摘要 |
An apparatus for overriding a valve actuator to move a valve stem to a second position includes an override body with a central axis. A piston is located within the override body. A bushing is non-rotatably carried within the override body. An override shaft is in threaded engagement with the bushing and extends through a sealed orifice in the override body. Fluid pressure applied to the piston causes the bushing to engage the valve actuator and push the valve stem, and alternatively, rotation applied to the override shaft causes the bushing to move linearly to engage the valve actuator and push the valve stem. |

1. An apparatus for overriding a valve actuator to move a valve stem from a first position to a second position, the apparatus comprising:
an override body with a central axis; a piston located within the override body; a bushing non-rotatably carried within the override body; and an override shaft in threaded engagement with the bushing and extending through a sealed orifice in the override body; wherein fluid pressure applied to the piston causes the bushing to engage the valve actuator and push the valve stem, and alternatively, rotation applied to the override shaft causes the bushing to move linearly to engage the valve actuator and push the valve stem. |
