Taco EBV

Hello,

I was wondering how the Taco EBV zone valve works. I understand the wiring and concept of the valve, however I haven't found anywhere that actually describes the flow of the valve. If the valve is normally closed does the flow go into A then out B? When the valve is activated does it flow from A through C?

I am looking for a valve that will divert the flow from the main line to a separate zone when activated.

Any help or suggestions would be appreciated.

Thanks,

Duane.

Two-Way

The Taco EBV are two way valves - go thru A-B.
The C port is plugged. And have N.O or N.C options when wiringg the head.

The Taco I series are mixing valves , utilizing the third port. The head does mixing, have sensor and outdoor reset capabilities.

Bypass valve

Singh,

Thanks for your reply. I am looking for a valve similar to the Taco EBV, but I would like it to divert the water.

Normal flow would be A through B. When a signal is received (thermostat) it will close the B output and open the C for a A through C flow.

I am not looking to mix, just divert the flow.

Any suggestions?

Thanks,

Duane.

Taco 560 series

The Taco 560 series will divert flow, but not 100%, like a true diverting valve would, but perhaps this will work in your application. For your reference I attached the catalog information. Please advise, if you have any additional questions.

Joe,

Thanks for the response. The Taco 560 may work, do you know how much will be diverted? Just a rough guess?

Thanks,

Duane.

Thanks Joe!

So you're looking for a zone control valve? You want the flow to bypass a radiator or zone unless the therm calls for heat, at which point it will flow through the radiator or zone and then back into the supply/return line, correct?

Don't know if this is against the rules or not, and if so, I apologize..

valves

Heather,

Thanks for the reply. I have been to pexsupply.com and that is where I originally found the Taco EBV. Most valves mix or just on off. I can't find something with three ports that will fully divert the flow from one port to another. I believe what I have now will work properly, just isn't what I originally designed, but workable.

Thanks,

Duane.

No problem. I work for a B&G distributor. When a new system is going up for either heating or cooling w/multiple zones we have a specific set up that involves "coil kits" and circuit setters...it ultimately results in each zone being individually operated off a single supply line by the bypassing or inclusion of each zone based on a call for heat/cooling.

Unfortunately, in pre-existing systems it's hard for us to provide ONE item that will successfully create a full-throttle bypass.

They don't give us a lot of training in solving those problems for customers, which is unfortunate. Most people expect us to be an authority, and rightly so.

Found a diverting valve...

Hello again,

I think I found a diverting valve from a company called Temco Controls. According to their tech guy, the flow enters the bottom port (C) and goes through port A when the valve is not energized. When energized the flow then is diverted to port B.

Very reasonable cost. Shipping is high when only ordering one, but gets more reasonable when ordering in quantity.

They also have a lot of other items that they developed and a very low cost.

Anyone have any experience with this company? Good? Bad?

Thanks,

Duane.
