VA-4233 Series Electric Valve Actuators
Description
VA-4233 Series Electric Valve Actuators use a
stepper motor to accurately position control
valves in HVAC applications. In the event of a
power failure, a spring in the actuator
automatically returns the valve to the full
stem-up position. These direct-mount,
spring-return electric actuators provide a
minimum 61 lb (271 N) force output for
floating, on/off, or proportional control, and can
be easily field mounted or ordered factory
coupled to Johnson Controls® 1/2 through
1-1/4 in. VG7000 Series Bronze Control
Valves, with no additional linkages required.
The VA-4233 Series can also be field mounted
to select Barber-Colman® valves, using
mounting kits available from
Johnson Controls. Proportional control models
include an AUTO stroke calibration feature
that eliminates the need for manual calibration
or adjustment after installation. Integral
auxiliary switches are available to indicate
end-stop position or to perform switching
functions. On proportional models, position
feedback is also available through a
proportional DC voltage signal. All models
feature a hand crank for manual positioning of
the valve, independent of a power supply.
Refer to the VA-4233 Series Electric Valve
Actuators Product Bulletin (LIT-977552) for
important product application information.
Features
designed for use in hot water, chilled water,
and steam applications, allowing for
universal application
automatic spring return returns the valve to
the full stem-up position, in the event of a
power failure
simple no-linkage mounting with AUTO
stroke calibration at installation
(VA-4233-GGx models only) reduces
installation time and cost
reversible stroke direction (VA-4233-GGx
models only) expands usability by allowing
switch-selectable direct or reverse action
optional auxiliary switches provide
adjustable switch points with line voltage
capability
0 (2) to 10 VDC, 6 to 9 VDC, or 0 (4) to
20 mA input (VA-4233-GGx models only)
provides enhanced control solutions
optional power supply output of 20 VDC at
25 mA (VA-4233-GGx models only)
provides power for external devices,
making the VA-4233-GGx an ideal
replacement for Barber-Colman retrofit
installations
manual hand crank allows for manual
positioning of the valve, independent of a
power supply
integral position indicator provides visual
indication of the valve stem position
1/2 in. conduit connector with 48 in. wire
leads meets national and local code
requirements for wiring, and allows easy
field wiring on retrofit jobs
