Instructions

Refer to the QuickLIT Web site for the most up-to-date version of this document.

Applications

The VA9208-Bxx-x Series On/Off Electric Spring

Return Actuators are direct-mount valve actuators that

operate on AC 24 V power at 50/60 Hz, DC 24 V

power, AC 120 V power at 60 Hz, or AC 230 V power at

50/60 Hz. These bidirectional actuators are used to

provide two position control on Johnson Controls®

VG1000 Series 1-1/4, 1-1/2, and 2 in. (DN32, DN40,

and DN50) ball valves in Heating, Ventilating, and Air

Conditioning (HVAC) applications.

The VA9208 Series Electric Spring Return Actuators

provide a running torque of 70 lb·in. (8 N·m). Integral

line voltage auxiliary switches, available only on the

VA9208-xxC-3 models, indicate end-stop position, or

perform switching functions within the selected rotation

range.

Installation

Install the ball valve with the actuator at or above the

center line of the horizontal piping (see Figure 1).

Special Tools Needed

• Johnson Controls® M9000-200 Commissioning

Tool or digital voltmeter

• T-20 TORX® driver

IMPORTANT: Use this VA9208 Series Electric

Spring Return Valve Actuator only to control

equipment under normal operating conditions.

Where failure or malfunction of the VA9208 Series

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 VA9208 Series Electric Actuator.

IMPORTANT: In steam applications, install the

valve with the stem horizontal to the piping. Failure

to follow this precaution may shorten the life of the

actuator.

IMPORTANT: Before specifying VA9208 Series

Electric Spring Return Valve 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, while others use different acceptance

criteria.

IMPORTANT: Do not install or use this VA9208

Series Electric Spring Return Valve Actuator in or

near environments where corrosive substances or

vapors could be present. Exposure of the actuator to

corrosive environments may damage the device’s

internal components, and will void the warranty.

Note: Depending on your application, you may position the assembly in any of the four 90° increments on the valve. Manual Override Wiring ! Use only the supplied manual override crank to reposition the actuator hub when using the manual override feature. IMPORTANT: Applying excessive torque to the manual override or operating the manual override with a power tool may damage the internal components of the actuator and cause premature failure. To reposition the actuator hub, proceed as follows: ! 1.
