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.
