Resideo V8043G1018 3/4-Inch Sweat Zone Valve with End Switch, 24V Normally Closed

The Resideo by Honeywell V8043G1018 is a motorized zone valve designed for hydronic heating systems to control water flow in individual zones. This 3/4-inch sweat connection valve operates on 24 volts and features a normally closed (N/C) configuration, meaning the valve remains closed when not energized, preventing water flow until called for by the thermostat.

Key Features:

• 3/4-inch sweat (copper) connections for soldering to copper pipe
• 24VAC low-voltage operation for safe integration with heating systems
• Normally closed design ensures fail-safe operation
• Integrated end switch provides feedback for system control and monitoring
• Powerhead actuator provides reliable motorized valve operation
• Suitable for hot water and glycol solution applications
• Compact design for tight installation spaces

This zone valve is commonly used in residential and light commercial hydronic heating applications, including baseboard heating, radiant floor systems, and multi-zone heating installations. The end switch allows the circulator pump to activate only when the valve is fully open, improving system efficiency and reducing wear on system components.
