    My main air vents: one is is Gorton #1 and the other one is Vari valve. There is hissing sound recently on Gorton. It is lukewarm when the steam boiler is cooking. The other main vent Vari valve is quiet, no hissing sound and always hot. I don't have enough space to install Gorton#2. Can I install Vari valve instead? How many Vari valve equal to one Gorton#1?
