Gorton Vapor Equalizing Valves for radiators are made with five sizes of air outlets. When the correctly sized valve is installed on each radiator, the system is balanced and equalized so as to provide fast, even, comfortable heating in every room. Larger sizes of Vapor Equalizing Valves should be installed on radiators farthest from the boiler and-in the coldest rooms. The small sizes are for radiators closer to the boiler and affecting the thermostat.
