I wouldn't put the other valve on the chiller inlet, but rather on the outlet. I have a valve assembly on my plate chiller outlet. It has a camlock QD (female) fitting, 90 degree elbow, a pair of 'T' fittings, two ball valves and a 1/2" NPT to 1/4" compression fitting. The two 'T' fittings each go to ball valves (next to each other) so that I can connect one to my recirculation fitting and the other to the fermenting vessel (hose through the opening). The NPT to compression fitting is where I have my thermometer sensor/probe, to get a solid reading once the wort has gone through the chiller. I also have a ball valve on the pump output side, to reduce the flow while the flame is still going. Once the fire is turned off, I can open it up all the way pretty quickly.

I'll take a picture of the chiller attachment setup and post it later.
Please do post a pic. That sounds interesting.

You don't need more precise control, you need a faster responding thermometer. The bimetals are slow so you over adjust the valve while you wait for the gauge to respond. Also, when in doubt, over chill it. There's nothing wrong with going 62F into the fermenter and letting it come up through the yeast exothermic reaction.

+1 on that... I use sensors (type K) connected to my Fluke 52II that respond more than fast enough. Plus, I don't need to worry about what my viewing angle is (can impact how you see the dial thermometers reading). It also allows me to have the reading without having to hover over the kettle/keggle or plate chiller.

I originally used the RebelSmart on my first plate chiller (dial thermometer on it) but it soon started to morph into what I have today. Hardest part is securing the QD's to what they connect to. Probably more to do with soaking in PBW to clean, rinsing well, and then not using any lube on the gaskets/o-rings. I do find them easier to use if I hit them with a bit of Star San solution first.

I agree. The reason I use gate valves is to control fly sparges. They're way easier to control than ball valves.

How fast can you go from wide open to fully closed??

Personally, I have zero issues controlling the flow from the ball valves in my system. I don't fly sparge, so I don't have to worry about that. While I can see a gate valve being useful in that case, I don't see ball valves really being much worse. IF the brewer knows how to control them. You can open it just a hair, or all the way to full open, to control the flow.

IMO/IME, it's really more a matter of learning your system and properly controlling things.
