Float box set-up and floats

Has anyone used this kind of float box, valves and floats?
Do they work well/maintain good constant levels if trying to maintain 3/4 - 1"?
Can warm/hot sap go thru valve into these without problems?
Thanks for the input

I think float will be to heavy to maintain 3/4-1"

I agree, I think you need more surface area. I think it would be ok in a storage or head tank but not in a feeder box, especially with the feed hole right in front of it.

Any suggestions regarding what type of float I should replace the SS ball with that has more surface area without putting out $100 for the commercial Leader rectangle floats?

make one. but put a vent in it. your stainless one will explode if it sees temps above 220 without a vent

Just drill a hole in the side of flask to vent? Or are they strong enough to deal with the higher temps?

whiskey flask maybe. depends on head pressure

what size is the box? might have one that fits some I made, some are older with lead solder. wound let one go for 50.00 total. if it works out.

Float box size is 15"L x 8"W x 5.5"H
Head pressure on float valve will probably be minimal. I usually keep topping off a 20 gallon stock pot on a propane burner just a bit higher than pan for my "pre-heater" and am planning on piping the hot sap from ball valve in stock pot into the float box valve.
Let me know if you have a functional float; it'd be much 'preciated.
My syrup is only for personal consumption, so the lead solder is ok; the diet coke will probably kill me before the lead does.
