The Honeywell MP918B1006 is a rugged, high-performance pneumatic actuator designed to modulate medium- to large-sized HVAC dampers. Operating via a rolling-diaphragm piston mechanism with an integrated spring-return safety feature, it delivers precise control and exceptional reliability. Its 3–13 psi spring range makes it ideal for variable-volume air systems requiring smooth fail-safe operation.
