Reznor 116002 Ventor Assembly

The Honeywell Home V8043E1012 is a robust, normally closed motorized zone valve engineered for precision flow control in closed-loop hydronic systems. Featuring a high-torque synchronous motor and a 3/4-inch sweat connection, this valve is a standard replacement for managing individual zone temperatures in residential and light commercial applications. It operates on a 24V AC power supply and includes an end switch to signal the boiler or circulator pump once the valve has reached its full open position. The low-profile actuator housing allows for installation in tight mechanical headers, while the manual opener lever provides quick system filling and manual override capabilities during power failures. Designed for fluid temperatures ranging from 40°F to 200°F and a maximum ambient temperature of 125°F, this zone valve assembly ensures reliable operation under high static pressures. Its 3.5 Cv rating provides the necessary flow capacity for efficient heat distribution across manifold systems and baseboard loops.

Technical Benefits

• High-Torque Actuation: The 60 Hz motor ensures positive shut-off against high differential pressures, preventing ghost flow in inactive zones.
• End Switch Integration: The internal SPST end switch simplifies wiring by providing dry contact closure for secondary equipment control.
• Simplified Maintenance: The replaceable motor and powerhead design allow for field repairs without draining the hydronic loop.
• Durable Construction: Built with a brass body and stainless steel shaft to resist corrosion and handle frequent cycling.

Common Questions

Can I manually open the valve during a power outage?
Yes, the manual lever can be moved to the 'MAN. OPEN' position, which mechanically bypasses the motor to allow gravity flow or system purging.

Does this valve require a specific mounting orientation?
The valve should be installed in a horizontal or vertical pipe run, but never with the actuator motor facing downward to prevent condensate or debris from entering the housing.

What is the maximum pressure rating for this model?
The V8043E1012 is rated for a 125 psi operating pressure and a 20 psi close-off pressure, making it suitable for most standard residential boiler systems.
