The Resideo by Honeywell 40003916-047 is a 120-volt electric powerhead designed as a direct replacement component for V4044A series zone valves. This powerhead assembly provides the motorized actuation needed to open and close the valve, controlling hot water flow in hydronic heating systems.

Key Features:

• 120VAC electrical rating for standard residential applications
• Direct replacement for V4044A zone valve models
• Motorized actuator for precise zone control
• Factory-tested for reliable performance
• Easy installation on existing valve body

This powerhead is commonly used in residential and light commercial hydronic heating systems where individual zone control is required. The powerhead mounts directly onto compatible V4044A valve bodies, eliminating the need to replace the entire valve assembly when only the actuator requires service.
