ML7425
Honeywell ML7284 non-spring return direct coupled damper actuators provide portioning damper control in HVAC applications. It uses a current or voltage signal from an electronic controller to position a damper at any point between fully open/closed.

Overview
Honeywell ML7425 spring return electric linear valve actuators provide analog output of 0 to 10 Vdc or 2 to 10 Vdc. An internal selector plug reverses the direction of action. They operate standard Honeywell valves in HVAC applications.
