Resideo V8043F5051 Valve
The Resideo V8043F5051 is a standard 1-inch hydronic zone valve designed for professional-grade control in closed-loop systems. This 2-way normally closed valve features a 1-inch sweat connection and operates on a 24VAC motor, making it a reliable choice for managing hot water circulation. Constructed with a heavy-duty brass body, a stainless steel stem, and a brass seat, this unit is built for long-term durability in high-demand residential and light commercial applications. The spring return zone valve mechanism ensures positive closure when power is removed, maintaining a 20 PSI maximum close-off pressure. This model includes a manual opener for system filling or emergency operation and a screwed terminal block for direct wiring. With a 3.5 Cv flow coefficient, it provides efficient fluid transfer while the integrated SPST auxiliary switch allows for seamless end-switch signaling to the circulator pump or boiler controller.
- Quick Fit Motor: The replaceable power head allows for service or upgrades without draining the system or breaking pipe connections.
- Reliable Close-Off: Rated for up to 20 PSI differential pressure, preventing ghost flow in large hydronic loops.
- Integrated Auxiliary Switch: The SPST end switch simplifies wiring for boiler and pump sequencing.
- Manual Override: Includes a manual lever to facilitate easy air purging and system testing during installation.
Commonly Asked Questions
How do I wire the V8043F5051 to a standard zone controller?
The motor leads connect to the 24V thermostat circuit, while the two terminals on the auxiliary end switch are wired in parallel to the boiler's "T-T" terminals or the zone controller's priority input.
Can the motor be replaced without removing the valve body?
Yes, this unit features a quick-fit design that allows the power head to be removed by pressing a release button or removing mounting screws, depending on the production series, without breaking the 1-inch sweat seals.
Is this valve suitable for steam applications?
No, the V8043 series is strictly designed for hydronic heating systems using water or glycol solutions and is not rated for steam pressure or temperatures.
