Johnson Controls VA-7482-0312 Electronic Valve Actuator Proportional 24V

The Johnson Controls VA-7482-0312 Electronic Valve Actuator This actuator has a proportional control system and this implies that the movement of this actuator will directly relate to an electrical signal. The VA-7482-0312 operates on a standard voltage of either 24 VAC or 24 VDC and accepts control signals of 0 to 10 VDC. This signal is normally coming from a building automation system and determines the position of the valve stem. The actuator is used to open or close the valve and therefore control the flow of air or water through the system.
