READ THIS INSTRUCTION SHEET AND THE SAFETY WARNINGS CAREFULLY
BEFORE INSTALLING AND SAVE IT FOR FUTURE USE
General features
VA9104 Series Actuators are direct-mount, non-spring return electric valve actuators
that operate on AC 24V or AC 100
driven actuators are used to provide accurate positioning on Johnson Controls
Series DN15, DN20, and DN25 ball valves in Heating, Ventilating and Air Conditioning
(HVAC) applications.
VA9104 Series Electric Non-Spring Return Actuators provide a running torque of 4 Nm.
IMPORTANT: Use this actuator only to control valves under normal operating
conditions. Where failure or malfunction of the 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 actuator.
Installation
Install the ball valve with the actuator at or above the centerline of the horizontal piping.
WARNING: Do not install or use this 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
To mount the actuator to a ball valve:
1. Rotate the valve stem manually several times using an adjustable wrench to break
the torque that may have built up during long-term storage.
Then, rotate the valve stem so that Port A on the valve is open.
Note: Two-way valves in the fully open position have the index marking on the top
of the valve stem, parallel to the direction of flow. Two-way valves in the fully closed
position have the index marking perpendicular to the direction of flow. Three-way valves
feature two index markings on the top of the valve stem, with one of the index markings
parallel to the common port (see Figure 3 and Figure 4).
2. Place the handle on top of the drive shaft as shown in Figure 5.
The handle is keyed and can only be mounted in one orientation.
3. Insert the M4 x 60 long machine screw into the hole in the handle.
Use a flat blade screwdriver to drive the screw into the drive shaft until the screw
is below the top of the handle.
4. Check that the actuator coupler and handle are in the fully 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.
5. Install the valve actuator over the ball valve mounting flange.
Depending on the installation, position the assembly in any one of four 90°
increments on the valve.
Note: For proper operation, the actuator must drive the valve counterclockwise to open
Port A when viewed from above the valve.

Selecting the direction of rotation
®
VG1000
VA9104-GGA actuators are factory set for Direct Acting (DA) mode and for a DC 0 to 10
V input control signal. In DA mode, a minimum control signal drives the actuator to the
full counterclockwise (CCW) position, and a maximum control signal drives the actuator
to the full clockwise (CW) position.
For Reverse Acting (RA) operation, a minimum control signal drives the actuator
to the full CW position and a maximum signal drives the actuator to the full CCW
position. To change the factory settings, remove the actuator cover and adjust
the switches on the circuit board.
Wiring
WARNING: Risk of Electric Shock Disconnect the power supply before
making electrical connections to avoid electric shock.
WARNING: Risk of Property Damage Do not apply power to the system
before checking all wiring connections. Short circuited or improperly
connected wires may result in permanent damage to the equipment.
IMPORTANT: Make all wiring connections in accordance with local, national, and
regional regulations. Do not exceed the electrical ratings of the actuator.
