Resideo V8043F1093 Valve
The Resideo V8043F1093 is a heavy-duty, 3/4-inch sweat connection zone valve designed for precision flow control in closed-loop hydronic systems. Built with a rugged brass body and a stainless steel stem, this 24Vac motorized zone valve is engineered to withstand static pressures up to 300 psi and fluid temperatures reaching 200°F. As a normally closed zone valve, it utilizes a reliable spring return mechanism to ensure a positive shut-off when de-energized, maintaining a maximum close-off pressure of 8 psi. The integrated normally open SPST auxiliary switch allows for seamless end-switch signaling to circulator pumps or boiler controllers, optimizing system sequencing. This 8 Cv high-flow valve features a convenient manual opener lever for system filling or emergency operation during power outages. For the contractor, the screwed terminal block facilitates rapid field wiring, while the compact powerhead design allows for motor or actuator replacement without breaking the plumbing line or draining the loop.
Key Benefits for HVAC Professionals- Efficient Serviceability: The complete powerhead or actuator motor can be replaced without removing the valve body from the line, significantly reducing labor time.
- Robust Construction: Combines a forged brass body with a brass seat and stainless steel stem for long-term durability in demanding heating applications.
- High Flow Capacity: Delivers an 8 Cv flow coefficient, ensuring minimal pressure drop across the valve in residential and light commercial hydronic loops.
- Simplified Wiring: Features a screw terminal block for secure 24V connections and an auxiliary end switch for direct boiler/pump control.
- Emergency Manual Override: Includes a manual opening lever that automatically resets once power is restored to the 24V motor.
Can the V8043F1093 be installed in any orientation?
For best results and to prevent moisture from entering the actuator, the valve should be installed in a horizontal pipe with the actuator head upright or at an angle no greater than 85 degrees from vertical. It should never be installed with the head pointing downward.
What is the purpose of the auxiliary end switch on this model?
The normally open SPST auxiliary switch is designed to close only when the valve is fully open. This provides a "dry contact" signal used to start a circulator pump or fire the boiler burner, ensuring the system only operates when flow is established.
Is this valve compatible with systems containing high oxygen levels?
No, this brass-bodied valve is specifically designed for closed-loop hydronic systems. Using it in open loops or systems with frequent makeup water (high dissolved oxygen) can lead to premature corrosion of internal components.
