How to wire a zone valve on a boiler.

has been my method, but if all the zones are takeoffs from a horizontal header above the boiler, with the piping going up, you could get some ghost flow without positive shutoff on all the supplies. In that case the valves installed on the supply might be better. Even high Cv flapper style valves generally have a 20 psi shut.
