Resideo V8043G1026 Valve
The Resideo V8043G1026 is a professional-grade 24V 1" sweat N.C. zone valve designed for straight-through flow control in closed-loop hydronic systems. As a staple for service contractors, this two-way motorized zone valve features a normally closed configuration with a high-torque actuator and a brass body assembly that handles fluid temperatures up to 200°F. The 1-inch sweat connections are engineered for direct integration into copper piping, and the 3.5 Cv flow capacity ensures efficient delivery for heating zones and fan coil units. This model includes an integral auxiliary end switch for sequencing circulators or boilers, effectively streamlining system wiring by eliminating the need for external relays during a call for heat. Field service is simplified by a removable powerhead and a replaceable actuator motor, allowing for repairs without the need to drain the entire system loop. The manual opener lever provides immediate override capability during commissioning or power loss, returning to the automatic position once 24Vac power is restored.
Key Benefits for Technicians:
- System Serviceability: The complete actuator powerhead and motor can be replaced without breaking plumbing lines or draining the hydronic circuit.
- Integrated Control: Features a built-in auxiliary end switch (50 VA pilot duty) to directly trigger secondary equipment like pumps or burner circuits.
- Durable Construction: Features a brass body, stainless steel stem, and EPDM rubber packing to withstand static pressures up to 125 psi.
- Manual Override: Includes a manual opening lever with a "locked-open" position for easy system filling, purging, or emergency operation.
- Compact Footprint: Designed to fit within tight baseboard enclosures and mechanical closets with minimal clearance requirements.
Common Questions & Technical Support:
Can the V8043G1026 be used in open-loop potable water systems?
No, this valve is strictly for closed-loop hydronic applications. Exposure to fresh, oxygenated makeup water will cause the internal rubber ball to deteriorate and fail prematurely.
What is the maximum differential pressure for this 1-inch valve?
The maximum close-off differential pressure is 20 psi. Exceeding this rating may lead to valve lifting or "water hammer" noise during closing cycles.
Does this valve require a specific mounting orientation?
It can be mounted in any orientation on a vertical line. If installed horizontally, the powerhead must be at or above the centerline of the piping to prevent moisture from entering the motor housing.
