Tools for a Variety of Needs
From palm-sized-but-powerful to industrial-strength
actuators, KMC ControlSet
®
actuators precisely and
efficiently control the most demanding applications.
These actuators were designed to provide continual,
dependable control of air dampers and valves in
building automation systems.
Advanced Features and Benefits
ControlSet actuators are available in different torque
ratings from 10 to 320 inch-pounds to satisfy almost
any damper or valve requirement. Every ControlSet
actuator directly couples to damper and valve shafts.
Linkage kits, however, are also available. Models are
available in two-position (two-wire or three-wire), tri-
state (three-wire floating), or proportional control (2–10
VDC and/or 4–20 mA).
Fail-safe models will drive the actuator to the desired
home position during a loss of power to the actuator.
Capacitor-driven fail-safe models provide switch-
selectable direction and (because extra motor torque
to overcome spring resistance on every cycle is not
needed) higher energy efficiency over spring-return
actuators. Also, spring returns drive much faster
and have excessive torque during fail-safe mode,
potentially damaging equipment, but capacitor-driven
actuators provide consistent torque during fail-safe as
well as powered modes.
In addition, ControlSet actuator installation couldn’t
be simpler. Slide the actuator over the shaft, position
and lock it, screw down the anti-rotation bracket, and
wire the terminals. Setup for proportional models is
a switch for CW or CCW rotation for an increase in
control signal voltage. Setup for fail-safe models is
another switch for CW or CCW rotation during a power
loss. All models also have a gear disengagement
feature to make manual positioning quick and easy.
First with the Best
KMC Controls, an ISO-9001 registered company, is
the only privately held manufacturer of a full line of
HVAC and building automation controls in the United
States. KMC’s ControlSet direct-coupled actuators
were the first in the industry to carry a full five-year
warranty. These actuators are designed to rigorous
performance criteria and manufactured in the U.S.A. to
the industry’s most exacting quality control standards,
and, as a result, they perform perfectly day in and day
out. Few manufacturers offer this kind of performance
because KMC’s commitment to extreme quality
production standards is unmatched.
To give ControlSet actuators a warranty for the long-
term, KMC instituted the most exacting quality control
program in the industry. The key elements in this
program include:
• Demanding production standards—Every KMC
production employee goes through comprehensive
quality control training and periodic retraining
to ensure quality procedures don’t drift from the
standard.
• Increased supplier expectations—Evaluated on
every shipment, KMC’s vendors must live up to the
toughest quality code in the industry.
• Zeroing in on zero defects—Every KMC actuator
made is functionally tested during the production
process. Sample units in each production run are
fully examined to ensure complete quality standard
compliance. The total quality control process is so
effective that KMC consistently records near zero-
ppm-defects in every product line.
