Johnson Controls VA-8122-1

VALVE ACTUATOR; ELECTRIC; 22# PROP CNTRL 5/16 INCH STRK 24 VAC; 0-10VDC INPUT; 22# FORCE;

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.
