honeywell 3 way zone valve question

PostBy: dave brode On: Sun Sep 29, 2013 9:50 pm

Hello All,

I'm looking for a 1" sweat, 3 way 24v zone valve. Anyone learned on the subject?

It looks to my dumb butt that VCZMS6100/E and VCZMR 6100/E are the same except for the flow rating. Sorry, I can't get the darned links to work .

Imagine a tee. The ports on the run would be A and B, the branch would be port AB

Dumb question: It states that stem up [actuator NOT energized] = "A" closes. Does that mean the with stem up [actuator NOT energized], the AB port is open to port B? And, with stem down [actuator energized], the AB port would close and A port would be open to B port?

I know, clear as mud...sorry

Thanks.

It is a two position valve then yes, it would be open to the A or B port, one when actuated and the other when not.

coaledsweat,

Yes, they are both listed as two position, "one/off". It states only that with stem up, A is closed.

It does not state if with stem up, flow is B to AB, and stem down, flow is A to B, and AB is then closed.

I hope so.

Thanks.

p.s.

It appears that the Honeywell are not plumbed the way I need. It looks as though the AB port is the inlet, and either A or B are open to AB, depending on on/off. The A and B ports are not connected in eithet on of off position.

It appears to me that the Taco are plumbed the a way that suits my need. Being, the "run" is open when the valve is "ON" and the "OFF" [or bypass mode] connects is one side of the run, and the branch.

I'd rather use the Honeywell, but the Taco would really make it simpler to plumb. Now, if they make one that's 24v, with an isolated end switch.....

Thanks.

Try blowing air through it to see for sure which ports connect.

Fwiw/fyi,

The honeywell valve that I linked to above is actually a diverting valve, flow is into bottom [branch, marked AB] and out either side [on run A or B]. Taco also makes this style, as well as what is called a bypass valve. The bypass style allows water to enter the run, and either flow through the run, or, bypass to the branch.

This link is broken, either the page no longer exists or there is some other issue like a typo.
