Fluid device actuator with manual override

摘要

Apparatus for use with a fluid device includes an actuator having a first condition and having a second condition responsive to air under pressure for providing force for operating the fluid device. An override mechanism connected with the actuator is manually engageable to override the force provided by the actuator. The override mechanism may include a handle having a first handle position and a second handle position. The override mechanism may include a latching mechanism for automatically latching the handle in the selected handle position. The latching mechanism may be lockable.
