Resideo V8043G1018 Valve

Resideo V8043G1018 Valve

The Resideo V8043G1018 is a heavy-duty 24V motorized zone valve designed for precise flow control in closed-loop hydronic heating systems. Featuring a 3/4" sweat connection and a normally closed (N/C) configuration, this low-voltage operator is a standard for professional contractors managing multi-zone installations. The internal end switch allows for seamless boiler control wiring, ensuring the circulator pump only activates when the valve is fully energized and open. Built with a high-torque motor and a manual opener lever, the V8043G1018 facilitates easy system charging and troubleshooting without requiring power. Its compact design allows for tight manifold spacing, while the stainless steel shaft and EPDM rubber plug provide reliable shut-off against high differential pressures. For technicians replacing older Honeywell or Resideo units, this valve remains a drop-in hydronic zone valve replacement that maintains system hydraulic balance and thermal efficiency.

Key Benefits

  • Universal Compatibility: Standard 3/4 inch sweat fittings and 24V operation make this a versatile choice for most residential and light commercial hydronic applications.
  • Integrated End Switch: Simplifies wiring by providing a dry contact closure to signal the burner or pump relay once the valve is open.
  • Manual Override: Includes a manual lever to open the valve for system bleeding or emergency operation during power outages.
  • Field-Replaceable Actuator: The power head can be serviced or replaced without breaking the plumbing line, reducing downtime and labor costs.
  • High Close-off Pressure: Engineered to prevent "weeping" or bypass flow even in systems with high-head circulators.

Common Questions

Can the V8043G1018 be installed in a vertical orientation?
Yes, this valve can be mounted in any position; however, it is standard practice to keep the actuator head above the piping to prevent moisture or sediment from entering the motor housing.

What is the maximum pressure rating for this zone valve?
The unit is rated for hydronic heating system pressures up to 125 psi, with a maximum fluid temperature of 200°F, making it suitable for high-temperature baseboard and cast-iron radiator loops.

How do I wire the end switch for a multi-zone controller?
The two yellow wires power the motor (24V), while the two red wires are for the end switch. The red wires should be connected to the 'T-T' terminals on the boiler or the zone controller to trigger the firing sequence.
