How jour Architect can write 
heating comfort and small coal 
bills into jour specifications 
When your architect includes Hoffman valves in 
your heating specifications, he is planning a warm, 
cozy home for you, because Hoffman Valves assure 
[1] Radiators hot from end to end—a few seconds 
after you turn on the steam heat. 
[2] Radiators that radiate heat noiselessly—no 
banging or thundering. 
[3] No disastrous water and steam leaks. 
[4] Automatic perfection. Hoffman Valves are 
made right then sealed against meddling or need 
for adjusting. 
And so you get complete warmth on low steam 
pressure—hence small coal bills. 
No. 1 Hoffman Air 
Valve. The rec¬ 
ognized standard 
for radiator vent¬ 
ing in one pipe 
systems. 
As soon as your steam system has been equipped with 
Hoffman Valves you will receive the Hoffman guaran¬ 
tee of five years’ perfect operation. Be sure to ask 
your architect about it. Send to our New York office 
for the booklet, “More Heat from Less Coal.”
