The Dole Valve Company 1913-1933 Carroll Avenue, CHICAGO, ILL. Manufacturers of High Grade Radiator Valves and Brass Specialties (DVENT1NG SEAT THE DOLE SYPHON AIR VALVE (7JVALVE CASING (non adjustable, automatic) For venting low pressure steam radia (2)SEATING PIN tors. Fully guaranteed for five years. It has the Venting Seat (1) of heavy con (3) FLOAT- struction, threaded and brazed into the valve casing. The Seating Pin (2) of finely machined hard metal is hydraulically WINNER CHA pressed to a perfect radius, while the OF FLOAT Float (3) is of light but strong annealed brass, which rises when water enters the (5)DIAPHRACM valve, positively preventing leakage. The Inner Chamber of Float (4) contains the (6)FLOAT REST proper amount of thermostatic liquid which forms a powerful gas when steam comes in contact with, the float; thus the diaphragm is expanded and the valve closed against the escape of either steam or water. The Diaphragm (5) is made from special spring bronze, convex in shape and cor- rugated. The Float Rest (6) is one piece of finely drawn brass open on four sides to permit water to drain through the syphon, and the Valve Casing (7) of beautiful dodecagon design, fashioned from finely drawn heavy brass presents an attractive exterior and at the same time forms perfect air channels inside the valve. The Base (8) of heavy drawn brass threaded on the interior to meet exterior threading on the casing is firmly brazed to insure great strength and durability. The Connecting Nipple (9)--one piece of extra heavy drawn brass has in. standard iron pipe thread, which conforms to the requirements of all radiators. A Syphon Lock Collar (10) made from extra heavy brass firmly brazed to the syphon prevents either accidental or intentional removal of the syphon from the valve. (Note, the valve can. be removed from the radiator without the syphon becoming detached). The Syphon (11)--one piece of annealed brass tubing, is perfectly formed to fit inside the radiator column. Assembled into the valve free from obstruction, thus preventing interference when the valve is attached to the radiator. Regarding the finish, the entire valve is finely nickel plated, of an artistic design and highly polished. A real "beauty" and it works. ^ List Price.......................................................................... $1.50 .
