The V8043B1027 is a two-position hydronic zone valve from Resideo, the brand that carries the Honeywell Home line of residential heating controls. It pairs a motorized actuator with a 3/4-inch sweat valve body to start and stop hot water flow to a single heating zone on a call from a thermostat or zone panel.

The valve is normally open. It passes flow with no power applied and closes when the actuator is energized. Normally open is the right choice where a zone has to keep circulating if the control power drops — freeze protection on an exposed loop is the usual reason to specify it.

The 3/4-inch sweat connections tie the valve into the supply piping, and the V8043B1027 handles supply water at operating pressures up to 300 psi.

The V8043 and V4043 series have been the reference zone valves in North American hydronic heating for decades, and most contractors still order them by the original Honeywell part number. The actuator head is field-replaceable, so a burned-out motor does not mean cutting the body out of the line.
