r Values New York Air Valve Corporation $11-621 Broadway New York THE "AIR-OUT" LINE SYPHON THERMOSTATIC NON-ADJUSTABLE "Air-Out" valves, (or eliminating air from steam radiators, operate by the expansion of a phosphor bronze diaphragm, soldered on the bottom of a brass float, containing a volatile liquid. This float is large in size, allowing ample capacity for the necessary pressure to operate the diaphragm. The seating pin at the top of float is made from nickel silver, as called for in United States Government specifications for Air Valves. Verdigris will not form on nickel silver--corrosion at the vent port is therefore reduced to a minimum.. We are making the " Air-Out" in a special straight Convector Type, for use on copper radiation. Specially adapted and guaran teed to work satisfactorily on one-pipe steam systems.
