Barber Colman Piston Damper Actuator w/ 8-13 PSI Spring w/ Clevis

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 boxes.
