I used that SS valve, I made a float out of a 1/9th size steam pan, it's about 4" x6" if that. I made a strap out of a piece of 20 ga SS, drilled several 1/4" holes 1/2" apart. I used them and the adjustment where the rod attaches to the valve body to adjust depth. I used machine screws to put a lid (made form the same 20 ga SS) on the pan it that the strap was bolted to with #8x32 machine screws. I'll try to get a photo of it in the morning. I used it for three years on my drop flue, ran it 1" after the first year, it worked good with my head tank being about 3' over the pans. I had to put another nut on the end of the rod to hold it vertical, one on each side, tightened very tight. I had about $12 in the float.
