The VA-748x Series Electric Terminal Unit Valve Actuator provides floating, proportional, or proportional control with 0-10V position feedback signal and electric fail safe function in HVAC applications. The compact design of this actuator series makes it suitable for installation in confined locations, such as fan coils, chilled ceilings, manifolds, and more.

The VA-748x Series Actuator is designed for field mounting onto Johnson Controls and competitors’ terminal unit valves. Due to the innovative concept of auto stroke detection, the VA-748x can be installed over most of the conventional terminal unit valves and pressure independent control valves (PICV) with variable strokes on the market.
