The Barber Colman M574-5520 is a pneumatic damper actuator designed for precise linear control in HVAC systems. Operating within an 8 to 13 psig spring range, it features a 4-inch stroke and a spring return mechanism that ensures the actuator returns to its fail-safe position upon loss of air pressure. This actuator is suitable for applications requiring reliable modulation of dampers and valves.
