Resideo V8043F1101 24V Zone Valve 1 Inch Sweat Normally Closed with End Switch

The Resideo V8043F1101 is a 24-volt hydronic zone valve designed for residential and light commercial hot water heating systems. This 1-inch sweat connection valve provides reliable zone control for radiant heating, baseboard, and other hydronic applications.

Key Specifications:

• 24VAC power supply for standard HVAC control compatibility
• 1-inch sweat (copper) connections for direct soldering to copper pipe
• 2-position normally closed operation - valve closes when de-energized for safety
• Integrated end switch for system interlock and boiler control
• Cv rating of 8.0 for efficient flow in residential zones
• Compact powerhead design for tight installation spaces
• Direct-mount actuator requires no linkages or adjustments

The normally closed configuration ensures the valve automatically closes during power failure, preventing unwanted heat flow to inactive zones. The end switch provides a low-voltage signal to activate circulators or boilers only when zones are calling for heat, improving system efficiency and reducing energy costs.
