Sporlan 481116 Gasket
The Honeywell V8043E1012 is a professional-grade 3/4 inch sweat zone valve engineered for precision flow control in closed-loop hydronic systems. Built for 24V low-voltage applications, this normally closed motorized valve features a 3.5 Cv flow capacity and a robust brass body with stainless steel stem construction to ensure long-term reliability in demanding contractor environments. This motorized zone valve utilizes a high-torque synchronous motor and a spring-return mechanism, providing a dependable shut-off against 20 psi differential pressures. Designed for high-efficiency hydronic heating systems, the 1000 series powerhead allows for complete removal or replacement without draining the system, significantly reducing downtime and labor costs during field service. The integrated auxiliary end switch (SPST) provides seamless integration for signaling boilers or circulator pumps, making it a versatile choice for multi-zone residential and light commercial projects.
Key Benefits for Technicians:
- Streamlined Installation: The 3/4 sweat connection allows for direct soldering into copper lines; ensure the manual lever is in the "OPEN" position during sweating to protect internal seals.
- Tool-Free Component Access: The V8043E1012 actuator can be removed from the brass valve body by depressing a single release button, facilitating quick swaps without breaking plumbing seals.
- Manual Override: Includes a manual opener lever for system testing and operation during power failures, automatically resetting once 24V power is restored.
- Durable Internal Seals: Features high-performance EPDM O-rings and a Buna-N rubber ball plug to withstand fluid temperatures ranging from 50 to 200 deg F.
Common Questions:
Is this valve compatible with open-loop domestic water systems?
No, this unit is strictly for closed-loop hydronic applications. Exposure to fresh, oxygenated makeup water will cause premature failure of the internal components.
Can the motor be replaced without replacing the entire powerhead?
Yes, the 24V synchronous motor is a field-replaceable component, though many contractors prefer replacing the entire Honeywell zone valve powerhead to ensure the linkage and end switch are also fresh.
What is the purpose of the four wires?
Two wires are dedicated to the 24V motor for valve actuation, while the other two leads connect to the integral end switch to dry-contact signal the boiler or pump to activate once the valve is fully open.
