VA-3100 Series Electric Valve Actuators
Description
VA-3100 Series Electric Valve Actuators use a
synchronous motor to accurately position
Johnson Controls® VG2000 Series Cast Iron
Flanged Globe Valves in HVAC and industrial
applications. These non-spring-return electric
actuators have a 675 lb (3,000 N) force output
for on/off (floating) or proportional control.
Integral auxiliary switches are available to
indicate end-stop position or to perform
switching functions. Position feedback is also
available through an isolated 2,000 ohm
potentiometer. All models feature a manual
hand crank for manual positioning of the valve,
independent of a power supply.
Refer to the VA-3100 Series Electric Valve
Actuators Product Bulletin (LIT-977283) for
important product application information.
Features
synchronous motor with pressure switches
provides a constant running speed and
establishes fixed closeoff forces
two-bolt coupler clamp provides quick and
easy coupling of the actuator to the valve
stem
on/off (floating) or proportional control
allows optimal choice of control signal
adjustable starting point, span, and action
(proportional control model only) provides
application flexibility and allows for easy
sequencing from only one output signal
0 to 10 VDC position feedback signal
(proportional control model only) provides
accurate valve position indication in
response to an input signal up to 10 VDC
auxiliary switches and feedback
potentiometer available on select models
provide independent verification of actuator
position
manual hand crank allows for manual
positioning of the valve, independent of a
power supply
Repair Information
If the VA-3100 Series Electric Valve Actuator
fails to operate within its specifications,
replace the unit. For a replacement actuator,
contact the nearest Johnson Controls
representative.
