Two-way on-off low voltage valves consist of an actuator and valve assembly for controlling the flow of hot water.

Works very well

Comments about 3/4" Sweat Connection Zone Valve, normally closed, w/ screw terminal block connection, 8 Cv (24v):
Retrofitted two of these in my hydronic heating system, coupled with a Honeywell controller. The system was built with pumps that do not isolate the water heater and one other zone when turned off (the heat continues to flow driven by the main circulator pump). By using these units I was able to eliminate this problem. It is important to note that this valve does not impede the flow to the heating loops to any noticeable degree (my water still heats very quickly), and that it can handle the higher heat needed for a hydronic system ... many valves do neither of the above.If you are not a professional or experienced plumber, I suggest that you fully dismantle the valve, removing the rubber seal sphere before sweating it in. The body has a lot of mass and requires quite a bit of heat and for an amateur like me this is the safest bet (otherwise I am pretty sure I would have burned the rubber and ruined the valve). Dismantling is just a few screws so pretty easy. The only thing to watch is that the actuator is spring loaded (normally closed) so you need to be sure to "wind" the spring to the right position (as it was when it was dis-assembled). I installed two this way and everything went well.These units have been running constantly for about a year now with no problems (I just purchased a third to keep as a backup as these are now critical parts of my system).
Bottom Line Yes, I would recommend this to a friend

Comments about 1" Sweat Connection Zone Valve, normally closed, w/ screw terminal block connection, 8 Cv (24v):
Honeywell is always the right product for my customers. Supplied house.com has always been dependable for me and the acquiring of boiler parts.
This is a very good product.
from Dyer, Indiana
The Honeywell zones valve were very easy to install (I replaced my old Dole zone valves)and they all work the very first time I activated them.
High flow, simple function, works well
from Park City, UT
My home hydronic heating system was designed only with pumps and no zone valves. Two of the pumps are on a "hot" loop (full boiler temperature), and did not isolate well - the result was that whenever the boiler pumps ran these loops heated even if their thermostats did not require them. In installed these valves along with a Honeywell switching relay to take the 120V for the pump and convert it to the 24V required by the valve. The great thing about this valve is the built-in end switch that is only closed when the valve is open - by using this with a relay (in the same Honeywell unit) it ensure that the pump is never dead-headed. See accessories for the Honeywell switching relay I used. The only reason I did not give it a 5 is that the connectors are external, so it looks a bit rough and will collect a lot of dust over the years (all 24V so meets code).

Quality product; easy install

Installed as additional zone back flow prevention to improve effeciency of floor radiant heat system. This is one of similar Honeywell items I have installed thru the years in similar systems. Installed correctly, will function for many years!
