Resideo V8043E1079 Valve
The Resideo V8043E1079 is a heavy-duty 1" sweat zone valve designed for precision flow control in closed-loop hydronic systems. Featuring a normally closed configuration, this motorized valve uses a reliable 24Vac spring-return actuator to ensure positive shut-off during power loss. Built with a rugged brass body and a stainless steel stem, the V8043E1079 provides a high 8 Cv flow capacity, making it ideal for high-demand baseboard radiators and convectors. The integrated SPST auxiliary end switch allows for seamless sequencing of circulator pumps or boilers when the valve reaches the fully open position.
Designed for easy field service, the entire powerhead can be removed or replaced without breaking pipe connections or draining the system. This 2-way zone valve handles up to 125 psi static pressure and 8 psi of close-off differential, ensuring quiet operation and preventing water hammer in professional HVAC installations. The unit includes 18-inch lead wires for straightforward wiring into the 24V control circuit.
Key Benefits- High-Capacity Flow: The 8 Cv rating minimizes pressure drop across the 1-inch sweat connections.
- Serviceable Design: Field-replaceable actuator and motor allow for maintenance without system drawdown.
- Integrated End Switch: Built-in SPST switch simplifies boiler and pump interlocking.
- Manual Override: Features a manual opener lever for system filling and emergency operation.
- Reliable Construction: Stainless steel stem and brass seat provide long-term durability in treated hydronic loops.
Can the V8043E1079 be used in open-loop systems?
No, this valve is designed strictly for closed-loop hydronic heating applications. Use in systems with constant makeup water containing dissolved oxygen will lead to premature failure of the internal rubber ball.
What is the purpose of the 18-inch leads?
The 18-inch lead wires provide ample length for routing to a nearby junction box or zone control panel, facilitating clean 24V electrical terminations.
Does this valve require specific mounting orientation?
The valve should be mounted with the actuator head above the piping. It can be installed in vertical or horizontal lines, provided the motor is not positioned below the valve body to prevent moisture damage.
