3/4" 2-Way Low Voltage Zone Valve, 24 VAC

Honeywell V8043E1061 Zone Valve – 3/4" Sweat, 24V Two-Way On/Off, Normally Closed

The Honeywell V8043E1061 is a two-position, low-voltage motorized zone valve designed for use in hydronic heating systems. It regulates hot water flow with a normally closed, straight-through valve body. This model features 3/4" sweat connections and operates on 24V AC power, making it suitable for residential or light commercial zoning applications.

Key Features

• Actuation: Two-way valve opens when powered, spring-returns to closed position when de-energized
• Manual Lever: Integrated manual opener allows for system fill or manual override during power loss
• End Switch: Not included with this model – for end switch versions, see V8043F series
• Replaceable Powerhead: Actuator can be serviced or replaced without disturbing plumbing connections
• Installation Orientation: Install with actuator in a horizontal position to prevent moisture ingress

Installation Considerations

This valve is designed for closed-loop hydronic heating systems and should be installed in accordance with local codes. Ensure system is depressurized and drained before soldering connections. Electrical termination is made via a screw terminal block. Always follow wiring diagrams provided by the manufacturer to ensure compatibility with zone panels or thermostats.

Contractor Notes

• Manual lever simplifies system purging during startup or service
• Actuator removal does not require draining the piping circuit
• Suitable for use with thermostatically controlled zone relay systems
• Use dielectric unions if installed on mixed-metal piping systems

Applications

• Residential hot water baseboard heating
• Zoned radiant floor heating systems
• Fan coil unit isolation in low-voltage systems
