Resideo V4043A1010 Zone Valve
The Resideo V4043A1010 Zone Valve is a 120Vac, two-way motorized valve designed for controlling the flow of water in hydronic heating and cooling systems. Built for professional-grade reliability, this 1/2 inch sweat zone valve features a normally closed configuration with a spring return to close mechanism, ensuring safety and flow control during power cycles. The 3.5 Cv flow capacity and 20 PSI maximum closeoff pressure make it ideal for high-head circulating pumps found in residential and light commercial baseboard or radiant installations. Constructed with a forged brass body, a stainless steel stem, and EPDM rubber packing, this unit withstands fluid temperatures ranging from 40 to 200 degrees Fahrenheit without degradation. Its integrated manual opener allows for system drainage and filling during commissioning, while the 18-inch electrical leads simplify wiring to the aquastat or zone controller. This valve provides consistent low-voltage zoning performance for contractors seeking a drop-in replacement for legacy Honeywell or Resideo systems.
- Optimized Flow Control: The 3.5 Cv rating ensures efficient hydronic distribution with minimal pressure drop across the loop.
- Durable Metallurgy: Features a brass seat and Buna-N rubber ball plug for a positive seal and long-term chemical resistance to glycol mixtures.
- Service Efficiency: The motor head can be replaced without draining the entire system, significantly reducing labor time on service calls.
- Manual Override: A dedicated manual lever assists in troubleshooting and gravity circulation during power outages.
Common Questions
Can the Resideo V4043A1010 be mounted in any orientation?
This valve should be installed with the actuator motor above the horizontal centerline of the piping to prevent moisture or sediment from accumulating in the motor housing.
What is the purpose of the manual opener on a motorized zone valve?
The manual lever is used to manually lock the valve in the open position. This is essential for air purging during initial startup or for emergency circulation if the 120V actuator fails.
Is this unit compatible with high-pressure boilers?
The V4043A1010 is rated for a 20 PSI close-off. It is critical to ensure your system's circulator pump head does not exceed this rating, or the spring return may fail to seat the ball plug properly against the flow.
