Zone Valve Replacement Heads

This collection covers Honeywell Home replacement heads and actuators for zone valves. It includes replacement heads for the V8043A, V8043B, V8044A, V8044E, V4043A and V4044A in 24 Vac and 120 Vac versions, some with end switches, and two-position actuators for VU52, VU53 and VU54 valve bodies.

Read the model number on the existing valve body or head before ordering, since normally open, normally closed, 2-way and 3-way versions are different. Match the voltage to the thermostat or zone control circuit, and choose a head with an end switch if it signals the boiler or pump. Turn off power before replacing the head.

Frequently asked questions

How do I know if the head or the valve failed?

If the valve opens when you move the manual lever but not on a thermostat call, the head or motor is the usual cause. A valve that will not move by hand needs a new body or cartridge.

Do I need to drain the system?

No. The head lifts off the valve body, so it can be changed without draining the loop. Turn off power first.

Which head fits my valve?

Match the valve series on the body (for example V8043A or V8043E), the voltage and whether you need an end switch.
