Resideo V8043E1137 Valve
The Resideo V8043E1137 is a heavy-duty, 2-way normally closed zone valve engineered for precision control in closed-loop hydronic systems. Featuring a rugged 1-inch NPT threaded connection, this motorized valve utilizes a high-torque 24Vac actuator with a spring return to close fail-safe mechanism, ensuring reliable shut-off during power loss. With a 10 Cv flow capacity and a 6.5 PSI maximum close-off pressure, it is optimized for managing high-volume flow in baseboard radiators and convectors without excessive pressure drops. The integrated normally open SPST auxiliary switch allows for seamless end-switch signaling to circulators or boiler controllers, while the 18-inch lead wires simplify field wiring for rapid deployment. Built with a forged brass body, stainless steel stem, and EPDM rubber packing, this Honeywell Home zone valve is designed for the high-cycling demands of professional HVAC installations where durability and quiet operation are non-negotiable.
Key Benefits- High Flow Performance: The 10 Cv rating provides superior flow rates for 1-inch piping, reducing pump head requirements in large residential or light commercial zones.
- Contractor-Friendly Installation: Equipped with 18-inch leads and a compact footprint that fits easily under baseboard covers.
- Manual Override Capability: Features a manual opening lever for system filling or emergency operation, which automatically resets once power is restored.
- Field-Serviceable Design: The powerhead can be removed or replaced without draining the system or breaking pipe connections, drastically reducing maintenance downtime.
- Critical Protection: The spring-return mechanism ensures the V8043E1137 fails closed, preventing uncontrolled heating in the event of an electrical failure.
How do I wire the end switch on a V8043E1137?
The end switch is a dry-contact SPST auxiliary switch. Connect the two red leads to the boiler's T-T terminals or the zone controller's end-switch input to trigger the burner or circulator only when the valve is fully open.
Can this valve be used in an open steam system?
No, the V8043E1137 is strictly for closed-loop hydronic systems. It is not compatible with systems containing dissolved oxygen or for use in steam applications; for steam, a V8043J model should be utilized.
What is the maximum operating pressure for this unit?
This specific 1-inch NPT model is rated for a maximum static pressure of 125 PSI and fluid temperatures up to 200°F, making it ideal for standard hydronic heating loops.
