Honeywell valves are normally closed. Just ask at the merchants for a 22mm(?) Honeywell Zone Valve. No need to take the old valve along. You will get the whole bit including the powerhead (the silver box). AFAIK you can't get just the brass valve body on it's own from a normal merchant.
Giblets, I've been able to order them via Plumb Center in the past
