Resideo by Honeywell V8043D1239 24V 1/2" Zone Valve with Inverted Flare Connection

The Resideo by Honeywell V8043D1239 is a normally open (N.O.) motorized zone valve designed for hydronic heating systems. This reliable zone valve features a 1/2-inch inverted flare connection and operates on 24 volts AC, making it compatible with most residential and light commercial heating control systems.

Key Features:

• 24V AC operation for standard low-voltage heating controls
• 1/2-inch inverted flare connection for easy installation
• Normally open configuration returns to open position when de-energized
• Motorized ball valve design for reliable, long-lasting operation
• Ideal for zone control in hot water or glycol-based heating systems
• Compact design fits in tight mechanical spaces

This zone valve is commonly used in multi-zone hydronic heating applications where individual room or area temperature control is desired. The normally open design ensures flow continues if power is lost, preventing freeze-ups in heating systems. The inverted flare connections provide leak-resistant installation without the need for soldering.
