OF FLOAT
Float (3) is of light but strong annealed
brass, which rises when water enters the

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.
