Resideo V8043E5012 Valve
For veteran contractors managing closed-loop hydronic systems, the Resideo V8043E5012 remains the industry standard for reliable flow control. This 2-way normally closed zone valve is engineered for high-performance fluid management in baseboard radiators, convectors, and fan coil units. Featuring a 3/4" sweat connection and a robust brass body, it handles static pressure ratings up to 300 psi with a 3.5 Cv flow capacity. The 24Vac motorized actuator utilizes a high-torque motor and a spring return to close mechanism, ensuring positive shutoff against a 20 pound maximum close-off pressure. The integrated normally open auxiliary switch (SPST end switch) provides seamless signaling to circulators or boilers upon full opening. Serviceability is optimized through the "Quick Fit" pushbutton powerhead, allowing for technical maintenance or replacement without disturbing the plumbing line or draining the hydronic loop. With its stainless steel stem and 18" leads, this unit ensures long-term operational stability in professional HVACR applications.
Key Benefits for Hydronic Systems- QuickFit Design: Snap-on actuator allows for rapid head replacement without breaking pipe seals.
- High Close-Off Capacity: Rated for 20 psi differential pressure to prevent ghost flow and leakage.
- Manual Override: Features a manual opener lever for system testing and operation during power outages.
- Durable Construction: Built with a forged brass body and stainless steel stem for corrosion resistance in non-oxygenated water.
- Integrated End Switch: Built-in SPST switch simplifies control wiring for boiler and pump sequencing.
