Resideo V8043A1029 Valve
The Resideo V8043A1029 Valve is a professional-grade hydronic zone valve designed for precise flow control in closed-loop heating systems. This 2-way normally closed motorized valve features a 3/4 inch sweat connection, allowing for seamless integration into standard copper piping systems. Built with a rugged brass body, a stainless steel stem, and a reliable brass seat, it is engineered to withstand fluid temperatures ranging from 50°F to 200°F. The 24Vac motorized actuator provides high-torque operation with a 3.5 Cv flow capacity and a 20 PSI maximum close-off pressure, ensuring positive shut-off and preventing ghost flows in multi-zone residential or commercial hydronic applications. For emergency situations or system testing, the integrated manual opener allows technicians to bypass the actuator, which automatically resets to the closed position once power is restored. Each unit comes equipped with 18 inch lead wires for straightforward electrical termination to your 24V transformer or zone controller.
Key Benefits for Technicians
- Field-Replaceable Components: The complete powerhead and motor can be serviced or replaced without draining the entire system or breaking pipe connections.
- High Close-Off Performance: Rated for up to 20 PSI maximum close-off, preventing leakage between zones even in high-head circulator applications.
- Durable Construction: Features a corrosion-resistant stainless steel stem and brass seat to extend service life in de-oxygenated water systems.
- Compact Profile: The space-saving design facilitates installation in tight boiler manifolds or baseboard enclosures.
- Manual Override: The lever-operated manual opener simplifies system charging and provides immediate manual control during power interruptions.
Common Questions
What is the proper application for this zone valve?
The V8043A1029 is specifically designed for closed-loop hydronic systems. It should not be used in open-loop or potable water systems where fresh, oxygenated makeup water is frequently introduced, as this can lead to corrosion of the internal components.
Can the actuator be installed after the valve body is soldered?
Yes, the actuator is designed to be installed after the brass body has been sweated into the line. To prevent damage to the internal seals and motor, it is highly recommended to remove the powerhead before applying heat to the 3/4 inch sweat connections.
Does this valve include an end switch?
The V8043A model is a standard two-wire valve. If your system requires a dry-contact end switch to trigger a boiler or circulator relay, you should verify if your specific configuration requires an 'E' or 'F' series model, as the 'A' series focuses on basic 2-position actuation.
