Resideo V8043E1145 Valve
The Resideo V8043E1145 Valve is a professional-grade 3/4 inch NPT motorized zone valve engineered for high-demand hydronic heating systems. Specifically designed for closed-loop applications, this 2-way normally closed valve provides precise on-off control of hot water flow to individual zones. Featuring a forged brass body, a durable stainless steel stem, and a rubber ball plug, the assembly is built to withstand a maximum static pressure of 125 psi and fluid temperatures up to 200°F. The 24Vac spring return actuator ensures the valve fails closed upon loss of power, while a built-in manual opener allows for system filling or manual override during outages.
For contractors, the V8043E1145 is valued for its serviceability. The complete powerhead and actuator motor can be replaced without breaking plumbing lines or draining the system, significantly reducing billable hours on maintenance calls. This model includes an integral normally open SPST auxiliary switch (end switch) rated for 50 VA pilot duty, allowing for simultaneous boiler or pump sequencing. With a 3.5 Cv flow capacity and a 20 psi close-off pressure rating, it delivers reliable performance in residential and light commercial baseboard or radiant installations.
Key Benefits for Technicians- Effortless Serviceability: Replace the entire powerhead or just the motor without draining the secondary loop or disturbing NPT threaded connections.
- Integrated End Switch: Includes a factory-installed SPST auxiliary switch for efficient boiler/circulator control.
- Manual Override: The exterior lever allows for manual operation during power failures, automatically resetting once 24V power is restored.
- System Protection: Spring return design provides a fail-safe position to prevent uncontrolled heating in the event of a power loss.
- Quiet Operation: Designed to minimize water hammer during the closing cycle, protecting system piping and sensitive components.
This valve is rated for a 20 psi maximum close-off pressure, which is standard for 3.5 Cv models in the 5000 Series line.
Can this valve be used in potable water systems?No, the Resideo V8043E1145 is strictly for closed-loop hydronic systems and should not be used in open-loop or potable water applications where oxygenated water is present.
How do I wire the end switch for boiler control?The valve utilizes 18-inch lead wires; use the two orange leads from the normally open SPST switch to complete the T-T circuit on your boiler controller or zone relay.
