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.
Features:
- Auto-commissioning simplifies installation,
since models require no adjustments in the
field
- Auto-shutoff actuator motor extends
actuator life by reducing drive time and
excessive motor wear
- Durable, heat-stabilized, plastic resin
enclosure allows the actuator to be used in
applications with fluid temperatures up to
203°F (95°C)
- Actuator can be mounted after the valve
body is piped, simplifying installation and
providing application flexibility
- Compact design allows for installation in
confined locations, such as fan coil
applications
- Operating status LED provides direct,
visual indication of the actuator operating
status
- Actuator can be rotated after it is mounted
on the valve body, simplifying installation
by allowing the actuator wiring entry to be
located in any direction
