Installation Instructions

Applications

The VA9208-AGx-x Series On/Off and Floating Point

Electric Spring Return Actuators are direct-mount valve

actuators that operate on AC/DC 24 V power. These

bidirectional actuators are used to provide accurate

positioning 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.

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.

VA9208-AGA-2 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 used

for environmental air handling purposes is an example

of the type of space for which these actuators are

configured.

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 Proportional

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.
