Pneumatic Damper Actuators
These actuators are designed for use in pneumatic
control systems to position air control dampers in
response to signals from pneumatic controllers.
The M556 is a large swivel-mounted actuator with
an adjustable crank arm having a clamp to fit a
1/2 in. O.D. damper shaft.
The M5xx Series damper actuators are used in
pneumatic control systems to position automatic
air dampers upon receipt of an air pressure signal
from a control device. These actuators are
equipped with right angle brackets and are
adaptable to air conditioning, multi-zone, heating,
ventilating, fan coil units, unit ventilators, mixing
boxes, and VAV terminal boxes. M573 and M574
are also available as post-mounted actuators.
The M583 is used in classroom type unit
ventilators. Special mounting kits are available for
adapting the actuator to the various makes and
models of classroom type units.
Features:
• Rigid, corrosion-resistant glass-filled nylon bodies.
• M556, M573 and M574 have 303 stainless steel shafts.
• M556, M573 and M574 available with or without
N800-0555-P positive positioner.
• The N800-0555-P positive positioner for M556, M573 and
M574 can be purchased separately.
