Technical Instructions A-Series Industrial Electric Actuators AUMA
Document Number A6V12035775
June 15, 2020
CAUTION:
Do not install or use the A-Series Industrial Electric 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.
Application
These actuators are ideal for use on valves for chillers, cooling towers, boilers, heat
exchangers and other outdoor applications. The actuators’ advanced electronics
assure reliable compatibility with virtually any analog control signal used in today’s
building automation and temperature control systems. The NEMA 6P rated housing
prevents any water ingress in outdoor applications. The built-in heater prevents any
condensation build-up inside the housing.
NOTE: Use a “liquid tight” conduit connector to maintain NEMA 6P rating.
