Belimo's SY series electric actuators have been designed to
mate with our HD(U), Grooved and SHP... series butterfly
valves and other quarter turn valve applications.
The patented gear drive mechanism provides for efficient, smooth
operation while allowing easy manual override at any time. Drawing
upon years of experience in the actuation industry, we have
incorporated the most desirable features into the SY product range.
All units have NEMA 4X ratings, easily visible position indicators,
international standard ISO5211 mounting systems, internal thermal
motor overload protection, heater, dual auxiliary Form C switches, and
easily accessible wiring termination points. Wiring diagrams, included
in all printed documentation, are also affixed to the outside of
the housing on the permanently attached product label.
The SY actuators are NEMA 4X rated and designed to meet
the needs of HVAC and Commercial applications. Offered on
Belimo standard and high performance valve series, these
actuators are available for on/off and modulating applications.
