Resideo V8043B1027 Valve

Resideo V8043B1027 Valve

The Resideo V8043B1027 is a trade-grade 3/4 inch sweat zone valve designed for precision hydronic control in closed-loop heating systems. This 24VAC motorized zone valve operates in a normally open configuration, ensuring flow continues when the system is de-energized—a critical fail-safe for specific zoning requirements. Built with a rugged brass body, a durable stainless steel stem, and a brass seat, this unit is engineered to withstand fluid temperatures up to 200°F and static pressures reaching 125 psi. The 3.5 Cv flow coefficient provides optimal throughput for residential and light commercial baseboard or radiator applications, while the 20 psi close-off pressure rating ensures reliable shut-off under standard circulatory loads. As a "quick fit" solution, the normally open zone valve allows for the replacement of the powerhead or motor without breaking the plumbing line or draining the loop, significantly reducing labor time for the service technician. This spring return to open valve includes 18-inch leads for straightforward wiring into the 24V control circuit.

Key Benefits
  • Serviceability: Powerhead and motor can be replaced without disassembling the valve body or draining the hydronic system.
  • Fail-Safe Design: Normally open operation ensures the zone stays active during power loss or control failure to prevent freezing.
  • Standard Compatibility: 3/4 sweat connections allow for direct integration into standard copper piping systems.
  • Industrial Materials: Stainless steel stem and brass seat construction resist corrosion in treated closed-loop water systems.
  • Compact Profile: Small footprint designed to fit within the cabinetry of most baseboard heaters and narrow utility closets.
Common Questions

Can this valve be used in an open-potable water system?
No, the Resideo V8043B1027 is designed strictly for closed-loop hydronic systems. The internal rubber components are not rated for the oxygen levels found in domestic water systems.

Does this valve include a manual opener lever?
Unlike the normally closed (N.C.) variants, this normally open zone valve does not typically include a manual opener lever as it is already in the open position when de-energized.

What is the maximum differential pressure for this model?
This valve is rated for a maximum closeoff pressure of 20 psi. Exceeding this limit may prevent the valve from sealing properly.
