Resideo V8043D1205 Zone Valve

Resideo V8043D1205 Zone Valve

The Resideo V8043D1205 is a professional-grade two-way hydronic zone valve designed for precise flow control in closed-loop heating systems. Featuring a Normally Open (NO) configuration with a spring return mechanism, this valve ensures system circulation in the event of a power loss, making it a reliable choice for critical heating zones. It operates on 24 Vac and provides a 3.5 Cv flow capacity, suitable for 1/2" inverted flare connections. Engineered for high-demand environments, the V8043D1205 handles a 20 psi maximum differential pressure and features a 15-second nominal opening time. This model is built without a manual opener, focusing on automated, lead-lag performance in hydronic baseboard or radiant manifolds. The 18-inch lead wires facilitate fast wiring to zone valve controllers or transformers, maintaining consistent close-off pressure and preventing ghost flows in complex residential or commercial plumbing layouts.

Technical Specifications & Benefits

  • Normally Open Operation: Vital for freeze protection and specific piping logic where failsafe flow is required.
  • Inverted Flare Connection: Designed for leak-free 1/2" inverted flare fittings, streamlining replacement in existing Honeywell or Resideo footprints.
  • High Flow Capacity: The 3.5 Cv rating ensures minimal pressure drop across the valve body during high-demand cycles.
  • Compact Powerhead: The motorized actuator is designed for tight clearances typically found in boiler trim or joist spaces.
  • 20 PSI Close-Off: Robust seating capability ensures the V8043D1205 prevents bypass leakage under standard circulator head pressures.

Frequently Asked Contractor Questions

Can the V8043D1205 be installed in an open-loop potable water system?
No, this low voltage zone valve is strictly for closed-loop hydronic heating and cooling systems where oxygen is not constantly replenished. Using it in potable water will lead to premature actuator failure and internal corrosion.

Is this model compatible with standard Honeywell V8043 base plates?
Yes, the Resideo V8043D1205 uses the standard 4-terminal/lead wire Honeywell zone valve footprint, allowing for easy head replacement on existing bodies in many retrofit applications.

What happens to the valve during a power outage?
Since this is a Normally Open (NO) valve, the internal spring return will automatically pull the valve into the fully open position if the 24V signal is lost.
