Description
The Honeywell M9174B1027 Proportioning Motor offers precise control over damper or valve position within residential and commercial HVAC systems. This versatile motor operates on standard household current (120 volts) and is compatible with a wide range of electrical frequencies (50Hz or 60Hz). A key feature is its adjustable stroke, allowing for customization of the travel distance of the shaft. This enables fine-tuning of damper or valve movement for optimal airflow control. The M9174B1027 incorporates a proportioning design, meaning the position of the damper or valve is directly related to the applied voltage. A higher voltage corresponds to a more open damper or valve, while a lower voltage closes it. This allows the system to precisely regulate airflow based on heating or cooling needs. An added benefit is the integrated auxiliary switch, which can signal the system when the damper or valve reaches a specific position. This motor finds application in various HVAC equipment, including air handling units and ductwork systems. Here, it connects to dampers or valves that control airflow throughout the building. The adjustable stroke and proportioning design enable precise control over airflow, leading to improved comfort and potentially increased system efficiency. The integral switch can provide valuable feedback on the damper or valve position for optimal system operation. At a weight of around 7.15 pounds, the M9174B1027 is easy to handle and install by qualified personnel within compatible HVAC units. Consult your specific unit’s manual for compatibility information before ordering.
