Resideo V8043F1101 Valve

The Resideo V8043F1101 is a 1-inch, 24Vac normally closed zone valve designed for standard-duty hydronic performance. Field-proven for localized flow control in baseboard radiation and convector applications, this low voltage zone valve features a manual opener that allows for manual bypass during power outages, automatically resetting to the energized state once current is restored. Built with a rugged brass body and stainless steel stem, the unit is rated for a high 8 Cv flow capacity and can handle a maximum differential close-off pressure of 8 psi.

For service technicians, the Resideo motorized zone valve offers a streamlined installation process. The sweat connection and compact lead-wire assembly allow for rapid integration into manifold systems without needing to disassemble the valve body. This model includes an integral end switch, enabling the sequencing of auxiliary equipment like circulator pumps or boiler fire-up upon valve opening. Operating at a 300 psi static pressure rating and supporting fluid temperatures up to 200°F, it is a reliable choice for HVAC zone control in closed-loop systems.

• Efficient Flow Control: High 8 Cv rating ensures minimal pressure drop across 1" piping systems.
• Contractor-Friendly Design: The powerhead assembly can be removed or replaced without draining the hydronic system or breaking plumbing lines.
• Reliable Closing: The spring-return mechanism ensures a positive seal when de-energized, preventing ghost flows in zone-controlled loops.
• Auxiliary Integration: Built-in SPST end switch provides easy feedback to the system controller or boiler for synchronized operation.

• Can the motor be replaced without removing the valve body? Yes, the motorized head is independent of the brass body, allowing for swap-outs without disrupting the wet piping.
• Is this valve compatible with glycol systems? It is designed for standard water systems; for high concentrations of system additives or glycol, verify the internal EPDM O-ring compatibility with the specific chemical mixture.
• Does this model require a specific mounted orientation? To prevent sediment buildup and motor overheating, it should be mounted with the actuator head above the horizontal centerline of the pipe.
