Patent ID: 8794589

Claim:
An actuator having an override apparatus, comprising: an actuator stem to couple a control actuator to a flow control member of a fluid valve; an override actuator to be selectively coupled to the control actuator via a connector in response to an override condition and selectively decoupled from the control actuator when the control actuator is in an operational state, the actuator stem having a first stem to be slidably coupled to one of the control actuator or the override actuator and a second stem to be coupled to the other one of the control actuator or the override actuator, the override actuator being positioned between the control actuator and a fluid valve, the connector being fixed to the actuator stem along a length of the actuator stem and positioned away from the control actuator and the override actuator to operatively decouple the control actuator and the override actuator when the control actuator is in the operational state; and a spring operatively coupled to the override actuator to cause the override actuator to move the actuator stem to a predetermined position via engagement with the connector in response to the override condition.
