Description
Product Summary
The Honeywell Residential V8043E1012 is a zone valve from Honeywell Residential, described by the manufacturer as: 24V zone valve (3/4" sweat 2 pos N.C. auxsw with 18" Leadwires) 3.5 cv 4 wires (2 red & 2 Yellow). It is rated for 24V, sized for 3/4" connections (sweat) and normally closed. It replaces MZV525E.
A zone valve opens and closes to let hot or chilled water flow to one zone of a hydronic system when that zone's thermostat calls. Its end switch, when equipped, tells the boiler or zone panel to start the circulator and burner. Signs of a failed zone valve include a zone that will not heat with 24 volts at the actuator, a zone that heats when it should not, or a boiler that will not start because the end switch never closes.
