Honeywell M9184D1021 Modutrol IV Non-Spring Return Actuator lb-in HVAC Control Valves & Actuators - 24VAC 150

The Honeywell M9184D1021 is a heavy-duty Modutrol IV proportional control motor designed for precise modulating control of dampers and valves in commercial HVAC systems. This non-spring return actuator operates on 24VAC power and delivers 150 lb-in of torque with fixed torque output throughout the entire voltage range, ensuring consistent performance.

Key Features:

• 135 ohm proportional control signal for Series 90 output controllers
• Adjustable stroke range from 90 to 160 degrees with 160-degree factory setting
• 30 to 60 second nominal timing for smooth modulation
• Dual-ended 3/8-inch square shaft with slotted and tapped ends on both sides
• Quick-connect terminals standard for easy installation
• Foot-mounted design with integral junction box providing NEMA 3 weather protection when mounted upright
• Auxiliary switch cams included; field-addable auxiliary switches supported
• Clockwise shaft rotation upon control signal increase (viewed from power end)
• Normally closed position (electric)
• Low power consumption at 15 VA during operation
