Features
Durable Construction — provides a degree
of protection from the elements for a single
Johnson Controls M(VA)9000 Series
Electric Actuator used in control damper,
ball valve, and iron flanged valve
applications.
Fully Enclosed Design — protects the
electric actuator from corrosion, rain,
freezing rain, sleet, and snow.
Impact-Grade Plastic Enclosure —
provides impact resistance.
Cover Constructed Using Ultraviolet
Inhibitors — extends service life by
preventing the cover from becoming brittle
or damaged by the sun or other
environmental elements.
Transparent Cover — allows the electric
actuator to be fully viewable without having
to disassemble the enclosure.

Description
The M9000-3xx Weather Shield Enclosures
are cost-effective and durable weather shields
designed to provide a degree of protection for
a single Johnson Controls®
M(VA)9000 Series Electric Actuator used in
control damper, ball valve, and iron flanged
valve applications. These weather shield
enclosures are manufactured to National
Electrical Manufacturers’ Association (NEMA)
specifications, and protect the electric
actuator from corrosion, rain, freezing rain,
sleet, and snow. The enclosure can be
mounted indoors or outdoors; however, the
enclosure may not prevent externally formed
ice from restricting the motion of the rotary
shaft.
Each enclosure is constructed of
impact-grade plastic that provides excellent
impact resistance. The cover features
ultraviolet inhibitors that extend service life by
preventing the cover from becoming brittle or
damaged by the sun or other environmental
elements. The transparent cover provides an
unobstructed view of the electric actuator
without having to disassemble the enclosure.
An appliance cord in the M9000-310 and
M9000-330 Weather Shield Enclosures
enable control wiring installation, and a
form-fitting seal prevents water or moisture
from entering the unit and damaging the
actuator.
