Honeywell 40003916-031 Replacement Motor

The Honeywell 40003916-031 Replacement Motor is a high-performance 120Vac powerhead designed specifically for the V4043B series zone valves. This normally open actuator features a 60 Hz electrical rating and 0.08 Amp current draw, ensuring consistent torque for hydronic applications. The assembly is built with 18-inch leadwires positioned on the same side as the manual lever, facilitating straightforward wiring in tight mechanical spaces. As a direct replacement for the 40003916-031/U, this unit is engineered for technical compatibility with both newer Series 6 valve bodies and older models when paired with a conversion kit.

For service technicians, this motor provides a reliable solution for maintaining spring return to open valve action. The integrated manual lever allows for easy system filling and manual operation during commissioning. Capable of handling ambient temperatures up to 125?F, the 40003916-031 ensures long-term operational stability in demanding HVAC environments. This complete head assembly includes the motor and housing, allowing for a total replacement of the electrical drive component without necessarily draining the entire system.

• Manual Override: Includes a manual lever for simplified system setup and troubleshooting.

Common Questions

• Is the 40003916-031 compatible with normally closed valves? No, this specific head is designed only for normally open V4043B series valves; normally closed models require a different actuator configuration.
• Can I replace this head without draining the hydronic system? Yes, if the valve body is a newer style or has been previously converted, the powerhead can be swapped without opening the water loop.
• What is the difference between the -031 and the -031/U models? These parts are functionally identical; the "/U" suffix simply denotes a "Universal" or Tradeline retail-packaged version of the same technical component.
