Honeywell Zone Valves

Honeywell Home zone valves and their replacement parts. The range covers V8043 2-way valves at 24 VAC, V4043 2-way valves at 120 VAC, V8044 and V4044 3-way diverting valves, plus replacement powerheads, actuators, motors, adapter kits and VC cartridges.

The model number tells you most of what you need. V80 models run on 24 VAC and V40 models on line voltage. The 43 is a 2-way valve and the 44 a 3-way diverting valve. The letter after it sets the wiring and position: for example, A is normally closed with lead wires, B and D are normally open, and E, F and G add an end switch that can start the boiler or circulator. The rest of the number covers the connection (sweat, NPT, flare or press), the size and the Cv rating.

A failed valve usually does not need a new body. If the valve still seats, replacing the powerhead or motor restores operation without draining the system. Match the head to the original suffix so the end switch and the normally open or normally closed position stay the same.

Replacement heads for all series are also listed in zone valve replacement heads. Zone panels and pump relays are in switching relays, and other brands are in all zone valves.
