There's an 4 inch exhaust stream that's emitting air at 2000CFM, I want to divide the exhaust in a 'Y' kind of outlet with two pipes.

If State 0- Exhaust out through one pipe.

If state 1- Exhaust out through another pipe.

What electrically actuated valves should I look at?

Thanks in advance.

You'll want a three way valve.

enter image description here

They come in a top down (above) and a one plane configuration (below).

The top down configuration allows L style and T style, while the one plane is typically only L style:

For your application a one plane configuration should suit you nicely, and is typically cheaper.

    $\begingroup$ Thanks @mark awesome, looking at vortexglobal.com/… just trying to find what's the best online market place for the same. Also where do you think I can find something that could resist high temperatures. ^_^ Thanks $\endgroup$

  • $\begingroup$ @touchaddict interesting site and useful information. As you know a lot goes into selecting piping material for an application and you know your application better than I do. All of that said, in applications I've run across, if a ball valve can handle the application, the three way valve can as well, so long as particle size isn't a major issue. If it is a concern, then filter out the particles before the valve. Or, if only one of the states is particle generation, consider using the t style and running through a leg (using the left leg for example, then switching between state 2 & 4) $\endgroup$

    $\begingroup$ youtube.com/watch?v=MqOplj2HSdE&t=1s this is the application I am trying to build. The input air is sooty carbon loaded, and I am in a rural part of India right now, so component sourcing is a little pain :) $\endgroup$

    $\begingroup$ look at this, ductingsystems.com/nordfab-parts-automatic-diverter-valve.html 4" valve system costs more than 2000$ crazy. hacks? $\endgroup$
