Johnson Controls VA7820-HGC-2 2-Switch Electric Valve Actuator Spring Return Proportional 0–10VDC 24V

The Johnson Controls VA7820-HGC-2 is an electric valve actuator, that enables controlling of air or water flow in electricity devices, which include air handlers, fan coil units and variable air volume boxes. It takes a 0-10 volt DC control signal and converts it into proportional travel of a valve or damper. This proportional control allows for correct and effective changes on the airflow or the water flow to ensure the right temperatures and comfort of structures. This employs spring return actuators; the valve goes back to a specific position when there is no control signal. This enhances another security measure and dependability within the facility’s HVAC systems.
