VA9104-xGA-3S Series Electric Non-Spring Return Valve Actuators Installation

Instructions

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

Applications

The VA9104 Series Actuators are direct-mount,

non-spring return electric valve actuators that operate

on AC 24 V power. These synchronous, motor-driven

actuators are used to provide accurate positioning on

Johnson Controls® VG1000 Series DN15, DN20, and

DN25 (1/2, 3/4, and 1 in.) ball valves in Heating,

Ventilating, and Air Conditioning (HVAC) applications.

The VA9104 Series Electric Non-Spring Return

Actuators provide a running torque of 35 lbin (4 Nm).

The nominal travel time is 60 seconds at 60 Hz

(72 seconds at 50 Hz) for 90° of rotation.

Installation

Install the ball valve with the actuator at or above the

centerline of the horizontal piping (Figure 1).

Special Tool Needed

To install the actuator, use a digital voltmeter or

M9000-200 Commissioning Tool.

IMPORTANT: Use this VA9104 Series Electric

Non-Spring Return Valve Actuator only to control

valves under normal operating conditions. Where

failure or malfunction of the VA9104 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 VA9104

Series electric actuator.

IMPORTANT: Before specifying VA9104 Series

Electric Non-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 VA9104

Series Electric Non-Spring Return Valve Actuator in

or near environments where corrosive substances or

vapors could be present. Exposure of the electric

actuator to corrosive environments may damage the

internal components of the device, and will void the

warranty.

Mounting the Actuator 4. Check that the actuator coupler and handle are in the full counterclockwise position as viewed from the top of the actuator. If not, press the actuator gear release and rotate the handle until the actuator coupler is fully counterclockwise. To mount the actuator: 1. Turn valve stem to position below. 2 Way FIG:VG1000 5. Install the valve actuator over the ball valve mounting flange.

Mounting the Thermal Barrier Figure 7 shows the optional M9000-561 Thermal Barrier. 2. Rotate the drive shaft to align marks on the top of the thermal drive shaft with matching marks on the valve stem. 3. Mount the thermal barrier onto the valve using the four included M5x16 mm machine screws and four M5 flange nuts. Tighten the screws to a recommended torque of 21 to 25 lb·in. (2.4 to 2.8 N·m) (Figure 9).

Wiring ! ! ! VA9104-AGA-3S and VA9104-IGA-3S WARNING: Risk of Electric Shock. Disconnect or isolate all power supplies before making electrical connections. More than one disconnect or isolation may be required to completely de-energize equipment. Contact with components carrying hazardous voltage can cause electric shock and may result in severe personal injury or death.
