Honeywell 40003916-526 Replacement Motor

The Honeywell 40003916-526 Replacement Motor is a critical service component for maintaining hydronic system integrity. Designed specifically for the V8043E 5000 Series Zone Valves, this 24Vac motorized actuator motor provides the high-torque performance necessary for reliable valve cycling. It features 18-inch leadwires for flexible wiring within tight enclosures and includes a built-in end switch to facilitate auxiliary equipment sequencing, such as burner or pump starts. This motor is the direct factory replacement for the 40003916-526/U and is engineered for quick field installation using the manual lever for simplified positioning during setup or power failure. For contractors managing hydronic heating zones, ensuring compatibility with the Honeywell zone valve replacement motor lineup is essential to prevent coil burnout and ensure consistent flow control. This unit delivers the standard 60 Hz electrical profile required for seamless integration into existing residential and light commercial low-voltage control circuits.

• Precise Compatibility: Direct drop-in replacement for V8043E 5000 series powerheads, ensuring proper mechanical alignment and torque delivery.
• Integrated End Switch: Simplifies system logic by providing a dry contact signal to the boiler controller or circulator relay once the valve is fully open.
• Manual Override: The manual lever allows technicians to manually open the valve for system filling, venting, or emergency operation.
• Extended Leadwires: 18-inch factory leads provide ample length for routing through junction boxes without the need for additional splicing.
• Industrial Build: Rated for continuous duty in high-ambient temperatures common to boiler rooms and mechanical closets.

Is the 40003916-526 compatible with older V8043A or V8043F series valves?
This specific motor is optimized for the 5000 series. While physical mounting may appear similar, electrical requirements and end switch configurations vary; always verify the powerhead series number before installation.

Does this motor include the replacement screws and gaskets?
This SKU typically includes the motor assembly and leadwires. Recovery of existing hardware or utilizing the specific Honeywell zone valve motor kit hardware is recommended for securing the motor to the mounting plate.

Can this motor be used in a 120V circuit?
No. This is a 24Vac replacement motor. Applying line voltage will result in immediate coil failure and potential damage to the transformer or zone controller.
