VA9203-xxx-xx Series Electric Spring Return Valve Actuators Product Bulletin2
VA9203-GGx-2Z Series Proportional Actuators
The VA9203-GGx-2Z Series Actuators provide
proportional modulation of VG1000 1/2, 3/4, and 1 inch
ball valves in HVAC systems that are controlled by an
electronic controller or positioner. The actuator
responds to 0 to 10 VDC or 2 to 10 VDC control
signals. With the addition of a 500 ohm resistor, the
actuator responds to a 0 to 20 mA or 4 to 20 mA signal.
A 0 to 10 VDC or 2 to 10 VDC feedback signal
indicates position and provides support for
master-slave applications.
Manual control system override applications are
supported through field wiring, and include:
• override to MIN position
• override to MAX position
• override to MIN, MID, and MAX position
The VA9203-GGA-2Z actuators include plenum-rated
cables and are specially configured for installation in
spaces used for environmental air-handling purposes,
other than ducts and plenums, as specified in National
Fire Protection Association (NFPA) 70: National
Electrical Code section 300.22(C), Other Space Used
for Environmental Air. The space over a hung ceiling,
when used for environmental air handling purposes, is
an example of the type of space for which these
actuators are configured.
VA9203-AGx-2Z Series On/Off and Floating
Point Actuators
The VA9203-AGx-2Z Series Actuators provide on/off
control or modulation of VG1000 1/2, 3/4, and 1 inch
ball valves in HVAC systems. Floating point control can
be provided from a triac or relay. On/off control can be
provided from a manual switch, controller, auxiliary
switch from a fan motor contactor, or similar device.
The VA9203-AGA-2Z actuators include plenum-rated
cables and are specially configured for installation in
spaces used for environmental air-handling purposes
other than ducts and plenums as specified in National
Fire Protection Association (NFPA) 70: National
Electrical Code section 300.22(C), Other Space Used
for Environmental Air. The space over a hung ceiling,
when used for environmental air handling purposes, is
an example of the type of space for which these
actuators are configured.
Available Weather Shield for Field Mounting Provides NEMA 3R protection for the actuator.
Override Control (Proportional Models Only) Supports manual control system override application through field wiring.

IMPORTANT: Use these VA9203-xxx-xx Series
Electric Spring Return Actuators only to control
equipment under normal operating conditions.
Where failure or malfunction of the electric actuator
could lead to personal injury or property damage to
the controlled equipment or other property,
additional precautions must be designed into the
control system. Incorporate and maintain other
devices, such as supervisory or alarm systems or
safety or limit controls, intended to warn of or protect
against failure or malfunction of the electric actuator.
IMPORTANT: Before specifying VA9203-xxx-xx
Series Electric Spring Return Actuators for plenum
applications, verify acceptance of exposed plastic
materials in plenum areas with the local building
authority. Building codes for plenum requirements
vary by location. Some local building authorities
accept compliance to UL 1995, Heating and Cooling
Equipment, whereas others use different
acceptance criteria.
