Honeywell V8043F5036 Motorized Zone Valve 3/4 in Sweat

Product Description

The Honeywell V8043F5036 is a low-voltage motorized zone valve designed for hydronic heating systems. Operating at 24 volts, this electronic valve controls hot water flow to individual heating zones, allowing independent temperature management across a structure. The actuator motor can be replaced without removing the valve body or draining the system, reducing downtime during service calls. Built with a metal body and a 3/4-inch sweat connection, it is suited for residential and light commercial hydronic applications. Licensed HVAC technicians and plumbers are the typical installers.

This zone valve is used in forced hot water heating systems where zoning is required. It fits into low-voltage zone control setups governed by a zone controller or individual thermostats. The 3/4-inch sweat connection makes it compatible with standard copper piping configurations found in residential baseboard and radiant floor heating installations. Its motorized actuator design integrates with 24-volt control wiring commonly used in hydronic zone panels.

Key Features

• Actuator motor replaceable without removing the valve body or draining the system
• 24-volt low-voltage operation for compatibility with standard zone controllers and thermostats
• 3/4-inch sweat connection for direct copper pipe installation
• Metal body construction for durability in pressurized hydronic systems
• Single-unit packaging for straightforward one-for-one replacement

Compatibility

Designed as an OEM-style replacement motorized zone valve for residential and light commercial 24-volt hydronic heating systems with 3/4-inch copper sweat piping.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber familiar with hydronic systems. Shut off system power and allow the system to depressurize before beginning work on any valve or piping. Use appropriate sweat-soldering tools and follow local plumbing codes when making copper connections. If replacing only the actuator motor, the valve body can remain in line without draining the system.
