EA40-A series actuators can proportionally position fuel valves, butterfly valves, dampers and other similar devices. An electrical holding circuit maintains position when at setpoint. The enclosed spring drives the actuator to the closed position on power interruption. The direction of the spring return is fixed and cannot be field changed. The direction of travel with increasing signal is field selectable as with the other analog input models. All versions are NEMA 4 rated. The EA40-A is compatible with the VB-7000 and VB-9000 valves in this catalog.
