Resideo V8043F1135 Zone Valve
As an HVAC technician, you know the Resideo V8043F1135 Zone Valve is a staple for reliable hydronic control in closed-loop systems. This 3/4" sweat connection valve is a two-way, normally closed unit engineered for cycling applications. It operates on 24 Vac and features a high-torque motor with a 15-second nominal opening time. With a 3.5 Cv flow capacity and a 20 psi maximum differential pressure, it ensures precise flow regulation without excessive noise. The integrated spring return to close mechanism provides a fail-safe shutdown, while the screw terminal block simplifies field wiring. This model includes a built-in, normally open SPST auxiliary switch (end switch) for signaling circulators or boilers. A manual opener is standard, allowing for system flushing or emergency operation during power loss. Its compact brass construction fits easily into baseboards, and the actuator can be serviced or replaced without draining the system, making it a preferred choice for professional low voltage motorized zone valve installations.
Key Benefits:
- Serviceable Design: Replace the entire powerhead or just the motor without breaking plumbing lines or draining the hydronic loop.
- End Switch Integration: The auxiliary SPST switch enables seamless coordination with circulator pumps or boiler controllers.
- Durable Construction: Features a brass body, stainless steel stem, and EPDM rubber packing for long-term sealing performance in systems up to 200°F.
- Ease of Installation: Compact footprint and screw terminal block facilitate 2-way straight-through piping in tight mechanical spaces.
- Manual Override: The side-mounted lever allows for manual opening during startup or power failures, automatically resetting once power is restored.
Common Questions:
Can I use the Resideo V8043F1135 in an open-loop system?
No, this valve is designed specifically for closed-loop hydronic systems. Using it in systems with dissolved oxygen (like domestic hot water) will lead to premature deterioration of the Buna-N rubber ball and seal failure.
How do I wire the V8043F1135 to a thermostat?
Wire the 24 Vac power to the screw terminal block. When the thermostat calls for heat, the motor energizes to open the valve; once fully open, the auxiliary end switch closes to complete the circuit to your burner or pump controller.
What is the purpose of the manual lever?
The lever allows you to manually lock the valve in the "Open" position. This is critical for air purging and gravity-feeding fluid throughout the system. Ensure the lever is set to "Auto" for normal thermostatic operation.
