Abstract: Embodiments of the present disclosure relate to a valve assembly that includes a valve configured to adjust a flow of fluid through a valve body of the valve assembly, an actuator configured to drive rotation of the valve, a gear assembly having a first planetary gear assembly and a second planetary gear assembly, where the first planetary gear assembly is coupled to the actuator, and where the second planetary gear assembly is coupled to the valve, and an override assembly coupled to the second planetary gear assembly, where the override assembly is configured to drive rotation of the valve independent of the actuator and without disengaging the actuator from the gear assembly.

Abstract: A system configured to adjust a seat of a ball valve includes a cam-actuated valve that is configured to be controlled via rotation of a stem coupled to a ball of the ball valve. The cam-actuated valve is configured to enable a flow of fluid at a first pressure to an opening extending through a body of the ball valve to drive the seat of the ball valve away from the ball when the cam-actuated valve is in a first position.
