Embodiments of the invention provide a system for controlling an analog valve positioner. The system includes a manifold, an analog valve positioner, and a valve actuator. The manifold has a manifold body which houses a spool valve, a powered control valve, and a microturbine generator. The control valve can change the position of the spool valve, and the microturbine generator provides power to the powered control valve. The manifold is in communication with the valve actuator, and the valve actuator is in communication with the analog valve positioner. The manifold also includes a controller, which senses a state of the spool valve and transmits position feedback to the valve actuator.
