Instructions

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

Applications

The VA9203-Bxx-2 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, or AC 85 to 264 V power at 50/60 Hz. These

bidirectional actuators are used for on/off control on

Johnson Controls® VG1000 Series 1/2, 3/4, and 1 in.

(DN15, DN20, and DN25) ball valves in Heating,

Ventilating, and Air Conditioning (HVAC) applications.

An integral line voltage auxiliary switch, available only

on the VA9203-xxB-2 models, indicates end-stop

position, or performs 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 Tool Needed

• Johnson Controls M9000-200 Commissioning Tool

or digital voltmeter

• T-20 TORX® driver

IMPORTANT: Use this VA9203 Series Valve

Actuator only to control equipment under normal

operating conditions. Where failure or malfunction of

the VA9203 Series Valve 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 VA9203 Series

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 VA9203 Series

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 VA9203

Series 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.
