direct replacement for Honeywell MZV zone valve?

It appears that one of my Honeywell MZV zone valves is not opening when aux heat is called for. I'll swap for a known working valve, but if it proves to be defective, are there any zone valves that will swap right in and have the same wiring, given these valves are no longer available? Thanks!
