Johnson Controls VA-8122 Proportional Valve Actuator (22 lb-in)

The VA-8122 Proportional Valve Actuator is an electric actuator that provides proportional control of valves with up to a 5/16 in. stroke in Heating, Ventilating, and Air Conditioning (HVAC) applications. This compact, non-spring return actuator has a 22 lb minimum seating force in a compact, easy-to-install package. Features: AUTOCAL pushbutton allows the actuator to define the control input range proportionally over the stroke simplified setup and adjust procedures decrease installation costs selectable direction of action, Drive Down or Drive Up, provides application flexibility wide range of control inputs meets the needs of most applications power failure detection and low voltage indication prevent data corruption of the actuator's memory and warns of insufficient supply voltage Light-Emitting Diode (LED) reduces commissioning time and displays operating status.
