Resideo V4043B1018 Zone Valve
The Resideo V4043B1018 Zone Valve is a heavy-duty, normally open hydronic zone valve designed for controlling flow in closed-loop systems. This 120V HVAC zone valve features a 1/2" sweat connection and a high-grade brass body with a stainless steel stem, ensuring durability under a 40-200 degree fluid temperature range. Designed for reliability, the V4043B1018 utilizes a spring return to open mechanism with a 3.5 Cv flow coefficient. The internal Buna-N rubber ball plug and EPDM rubber packing O-ring provide a tight seal against a 20 PSI maximum closeoff pressure. This specific model lacks a manual opener, focusing on automated operation via 18" electrical leads. It serves as a dependable Honeywell V4043 replacement for technicians managing flow control in residential or light commercial heating applications where 120Vac power is required for the motorized zone valve actuator.
Key Benefits for Contractors
- High-Temperature Reliability: The V4043B1018 handles fluid temperatures up to 200°F, making it ideal for high-temp hydronic loops.
- Corrosion Resistance: Engineered with a stainless steel stem and brass seat to minimize scale buildup and premature failure.
- Consistent Closeoff: The Buna-N rubber ball ensures a positive seal, preventing ghost flows and improving system efficiency.
- Direct 120V Integration: Eliminates the need for a step-down transformer when 120Vac signal power is available at the controller.
Common Questions
Is the V4043B1018 suitable for steam applications?
No, this valve is rated for a 40-200 degree fluid temperature range and is intended for water-based hydronic systems, not steam service.
Can I manually bypass this valve if the motor fails?
This specific model does not include a manual opener. It is a normally open zone valve, meaning it will revert to the open position upon loss of power or motor failure.
What is the maximum pressure differential this valve can handle?
The V4043B1018 is rated for a 20 PSI maximum closeoff pressure. Exceeding this limit may result in the valve failing to shut off flow completely.
