Damper Actuators

Performance,
Reliability and Low Power Consumption
Belimo damper actuators are
designed for use in a wide variety of HVAC applications ensuring performance,
reliability and lower power consumption. With a comprehensive torque range (9
to 1400 in-lbs) suited for damper sizes as small as 4 inch round allowing the
ability to direct mount on standard damper shafts or jackshafts. Actuators are
suited for control dampers, air handlers, economizer units, VAV terminal units,
fan coil units, fan shutters, and unit ventilators.
Belimo manufactures actuators for
smoke and fire dampers in ventilation and AC systems. These actuators have a
torque range of 18 in-lbs to 180 in-lbs when operating at 350°F. They have a
torque range of 18 in-lbs to 180 in-lbs @ 350°F. To ensure safety, the
fire and smoke actuators meet all codes for U.S. commercial buildings. They
pass UL 555 & UL 555S at 350ºF and are tested for 30,000 open-closed cycles
with approved dampers. Belimo fire and smoke damper actuators exceeds UL’s
requirement of 20,000 cycles at damper static load.
Control Valves

High Performance
Solutions
Belimo offers a complete range of
innovative pressure dependent and pressure independent valves to meet your
system’s needs and provide optimal flow control valve solutions. Our pressure
dependent products include globe valves, ball valves, and butterfly valves,
while our pressure independent products include mechanical valves (PIQCV),
electronic valves (ePIV), and the Belimo Energy Valve, an advanced IoT
cloud-connected valve that optimizes coil performance. Belimo valves help to
improve energy efficiency and reduce maintenance costs.?
Sensors / Meters
