Abstract:
Apparatus to increase a force of an actuator having an override apparatus are described herein. An example fluid control system includes a first fluid control apparatus to fluidly couple a control fluid supply source to a control actuator via a first passageway. The control fluid supply source provides a control fluid to move a control actuator member of the control actuator in a first direction or a second direction opposite the first direction when the control actuator is in the operational state. A second fluid control apparatus is in fluid communication with the first fluid control apparatus and is configured to fluidly couple an override actuator to the control actuator via a second passageway when the control actuator is in a non-operational state. The override actuator is operatively coupled to the control actuator.
