Honeywell Zone Motor Valve Compatible Replacement Options

SouthernLightsPM

Hi There,
I manage a 30 year old, 6 storey apartment building that used gas fired hot water baseboard heaters in all units. The baseboard heaters use Honeywell V8043C1058 zone motor valves, which are now discontinued. I am comparing replacement options for this issue since, given the age of the system, replacement parts are a necessary item. Before I came on board, previous maintenance staff had been replacing the zone motors only, when the heaters stopped working (ie: valve stuck either open or closed). This appeared to provide a temporary solution unitl the new motor wore out. 2 years ago, we started replacing the entire zone motor valve assembly when this issue was reported, which was a viable solution when the model number above was still available.

Current options under consideration are:
1. Rebuilding the current zone motor valves with available kits, and re-installing.
2. Purchasing as many of the Honeywell V8043C1058 as we can get our hnds on and either a) replacing all remaining units immediately or b) keeping them in stock and replacing only when there is a failure. (we have fully replaced 20 of the 100 units in the building so far)
3. Finding a compatible alternative manufacturer part that will work with our system to use instead of the Honeywell.

Any suggestions, alternatives, considerations to take into account, appreciated!

If you're going to sweat in new zone valves, then installing isolation valves and unions could save time down the road. If there's room for it.

Not quite sure what you mean by compatible here. Generally a zone valve is either open or closed, and generally it is controlled by a simple electrical signal to power it. Some are power open/spring closed, some require power both ways, but that is a control issue.

The other considerations are lay length in the piping and diameter.

Those zone valves have two basic parts: the valve and the operator (or actuator). If the valve is OK, why not just continue replacing the operators? They are still available. Part #40003916-026.

If you're looking to replace the entire zone valve, I recommend Caleffi zone valves as I think they're more rugged.

Part # for V8043C power head assembly is 40003916-011. The -026 is for V0843E.
Part # for motor only 802360JA

We have installed hundreds of Honeywell zone valves in the past. The ones that seem to last the longest are on systems with properly sized circulator pumps and/or pressure bypass valves. It seems like your not getting much time out of the actuator (zone valve head).

Is there any chance you have a high head circulator that is causing the zone valves to fail prematurely? For example, in my own house, I installed three Honeywell zone valves in 1991. The zone valves never gave me issues in the thirteen years they were in use.

We stopped installing Honeywell zone valves on new systems as the quality is not the same as it used to be. Today we much prefer Taco and Caleffi over Honeywell.
