THE HONEYWELL M9184C1031 MODUTROL Motor Actuator 50/60HZ. 90 DEG ADJ STROKE. 30-60 SEC TIMING. 150 LB-IN TORQUE. TAPPED DUAL END Shaft.
Overview
The Honeywell M9184C1031 is a modulating non-spring return damper/valve actuator, designed for control systems that drive it directly. It is foot-mounted and delivers 150 in-lb torque at 24 VAC. This actuator includes two internal auxiliary switches for position feedback or interlock logic, making it ideal for BMS or control integration.
It is commonly used in HVAC, boiler, and combustion control systems where proportional or modulating control is required, rather than simple open/close or spring return action.

Applications
The Honeywell M9184C1031 actuator is used in control systems requiring modulating motion such as:
-
HVAC dampers (airflow control)
-
Valve actuation in heating or cooling systems
-
Combustion dampers in boiler systems
-
Building automation and BMS systems requiring position feedback
-
Systems that need precision proportional control rather than just two-position motion
Its internal auxiliary switches support reserved signal paths, e.g. indicating end positions or fault conditions.
Benefits
-
Provides precise modulating motion for control systems
-
Internal auxiliary switches add feedback or interlock capability
-
No spring-return means actuator stays in the commanded position without a power draw
-
Robust mechanical and electrical design for reliability
-
Suitable for control environments demanding fine adjustment
