“I've been using these for a while now. These are on a completely different level then your standard Honeywell one's. The CV rating is similar to the Honeywell zone valves but these use less energy to operate. These look much more professional, easier to wire, has a light to inculcate what's going on. Yes these are more expensive but for me the value is there. Plus they're the sexiest zone valve I've seen to date. If they had a built in flow control then I'd be happier but no big.”
