VA-748x Series Electric Valve Actuators provide floating or proportional control in HVAC applications. The compact design of this actuator series makes it ideal for installations in confined locations, such as fan coil applications. The VA-748x Series Actuator is designed for field mounting onto the terminal unit valves made by
Johnson Controls and its competitors. Due to the innovative concept of auto stroke detection, the VA-748x actuator can be installed over most of the conventional terminal unit valves in the market and pressure independent control valves with variable strokes.
