Resideo V8043A5029 Valve
The Resideo V8043A5029 is a jobsite standard for hydronic control, engineered as a two-way, normally closed 3/4 inch sweat zone valve. Operating on a 24Vac motorized actuator, this valve utilizes a spring return mechanism to ensure positive closure during power loss or thermostat satisfaction. Built with a rugged brass body, stainless steel stem, and a brass seat, it is designed to withstand the rigors of closed-loop heating systems. The 3.5 Cv flow capacity provides efficient circulation, while the unit’s 20 PSI close-off pressure prevents seepage in high-head applications. For commissioning or emergency troubleshooting, the integrated manual opener allows technicians to bypass the motor. This quick-fit model includes 18-inch lead wires for straightforward integration into low-voltage zone control panels or transformers, making it a reliable drop-in replacement for residential and light commercial boiler systems.
Key Benefits for Technicians:- Standard 24V Actuator: Simplifies replacement and wiring within existing hydronic heating systems.
- Sweat Connection: Provides a permanent, leak-free seal on 3/4 inch copper tubing.
- High Close-Off Rating: The 20 PSI maximum differential ensures the valve shuts tight against pump head pressure.
- Manual Override: Allows for manual system filling and air purging without requiring power.
- Compact Footprint: Designed for tight mechanical rooms and manifold installations where space is limited.
Does this valve require an end switch?
The V8043A5029 is a two-wire model intended for basic on/off operation; if your application requires a four-wire setup to trigger a circulator or boiler, confirm your wiring requirements before installation.
Can the actuator be replaced without draining the system?
Yes, the quick-fit design allows the motor and actuator assembly to be removed from the valve body without breaking the hydronic seal, reducing downtime during service calls.
What is the maximum fluid temperature rating?
This Resideo zone valve is rated for standard hot water applications up to 200°F (93°C), making it suitable for high-temperature baseboard and radiator loops.
