Resideo V8043F1093/U 24V Zone Valve 3/4 Inch Sweat

Product Description

The RESIDEO V8043F1093/U is a two-way, normally closed, low-voltage zone valve designed to control the flow of hot water in hydronic heating systems. Operating at 24 volts, it combines an actuator and valve assembly in a single unit, opening on a call for heat and closing when the demand is satisfied. The 3/4 inch sweat connection suits copper pipe installations standard in residential and light commercial hydronic systems. Screw terminal wiring simplifies field connections for HVAC technicians and plumbing professionals who install and service zoned hot water heating equipment.

This zone valve is used in hydronic heating applications where multiple zones require individual flow control. Typical installations include residential baseboard systems, radiant floor heating loops, and fan coil units served by a common boiler. The normally closed design ensures no flow occurs during a power loss or when the zone is not calling for heat, which is standard practice for zoned hydronic systems. The 3/4 inch sweat end connection is compatible with standard copper tubing used throughout residential and light commercial plumbing and heating installations.

Key Features

• 24-volt low-voltage actuator integrates with standard thermostat and zone control wiring
• Normally closed operation stops flow automatically when the zone is not calling for heat
• 3/4 inch sweat end connections for direct soldering to copper pipe
• Screw terminal wiring block simplifies field connections and reduces wiring errors
• Two-way on-off design provides straightforward open or closed flow control

Compatibility

Designed as an OEM-style replacement for 24-volt normally closed zone valves used in residential and light commercial hydronic heating systems with 3/4 inch sweat connections.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber familiar with hydronic heating systems. Shut off the boiler and allow the system to cool before cutting into the piping. Solder the sweat connections with the actuator removed or protected from heat per standard practice to avoid damaging the valve internals. Low-voltage wiring to the actuator terminals must comply with NEC guidelines for Class 2 circuits.
