The M556 piston damper actuator, post mounted, is designed
for use in a pneumatic control system to position an air control
damper in response to a signal from a pneumatic controller.
These actuators can be used for either proportional or two
position applications. Other applications include the control of
variable fan inlet vanes, centrifugal refrigeration compressor
inlet vanes, and butterfly valves.
The M573 and M574 Series Piston 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 can be used for either proportional or
two position applications.
The M573 and M574 actuators are equipped with right angle
brackets and are adaptable to air conditioning, multi-zone,
heating, ventilating, fan coil units, unit ventilators, and mixing
Includes Right Angle Mounting
Bracket, Ball Joint, push Rod and
Crank Arm for 1/2"
