Installation
Install the ball valve with the actuator at or above the
center line of the horizontal piping (see Figure 1).
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.

Actuators Installation Instructions
IMPORTANT: Do not install or use this VA9203
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.
