Abstract
A valve actuator control system for use with a valve actuator may include two pump assemblies, two control valve assemblies, two transducers, a fluid reservoir, and a controller assembly. The controller assembly may actuate the pump assemblies to direct fluid from the fluid reservoir to the valve actuator, and may actuate the control valve assemblies to direct fluid from the valve actuator to the fluid reservoir. A method of actuating a valve actuator using a valve actuator control system may comprise sending a signal to the valve actuator control system, injecting pressurized fluid from a fluid reservoir of the valve actuator control system into a first chamber of the valve actuator, discharging pressurized fluid from a second chamber of the valve actuator into the fluid reservoir, and actuating the valve actuator from a first position to a second position.
