Can anyone tell me if I can escape installing a flow cxontrol valve by installing a taco ifc pump?

That's what Taco's spec sheets claim.

IFC circ or flow control valve

One thing I have learned about IFC circulators is they work FAR better on the supply rather than the return. Other than that, if the chart for the circ says you are OK, you probably are.

If I'm not mistaken, there should be a flow check valve on both sides of a zone, am I right?

Flow Check Valves

You only need one flow check device.

The TACO IFC circs are awesome.

Only problems I see in the future until everyone starts using them is if the flow check in the circ goes bad, is it easy to replace it? Heating techs will need to start to make sure their circ is a 007 or a 007IFC when replacing them. I am sure some lazy techs will just throw in regular circs in a pinch, because they are not stocking the IFC circs on their trucks yet.

I just did a job with them and loved them because of ease of installation and clean up of the looks of the piping.

I think all circulators should be made like this.
Think about it.
If you are installing/using a circulator, you are wanting to push matter one way, is there any reason why you would want it differently?

Lets remember the purpose for a flow check valve is to act as a check valve AND stop the flow of gravity heating when the zone is shut down and the boiler is running for other zones.

As stated above as long as the pump curve allows it. It does change the pump curve a little. We also have not seen the longevity of these check valves yet. We know a flow check is Good for about 20 years. Then just drop another disk assembly into it and your good to go. Of course these flow checks add more resistance to the system the IFC's as do zone valves.
