Here's the Valve 



for You 



REASONS— A ROUND DOZEN 



Can be repacked under full steam pressure. 



The only valve that comes packed, ready for service. 



All parts are renewable. 



Passages through the body are free and unobstructed, as the 



smallest area is in excess of that of the connecting pipe. 

 The seating surfaces are regrindable. 

 It is warranted for working steam pressures up to 150 pounds. 



Ordinary valves run from 60 to 125 lbs. pressure. 

 The body is made of special close-grained iron — pipe expansion 



won't cause it to leak as In the case of other valves. 

 The seat and disc are of durable nickel alloy. 

 The stem is of high tensile bronze. 



All other parts are of genuine Lunkenheimer Steam Bronze. 

 Easy-gripping handwheel. 

 Every valve is stamped with an arrow indicating direction of 



steam flow. 



Simplicity of design in any mechanical device spells strcngtii and long service. Complex, complicated, 

 involved and intricate mechanisms are to be avoided as a plague. 



A boy can see and understand the working of the Lunkenheimer Valve. It's as simple as 2 and 2. And 

 just as surely as 2 and 2 make 4, not sometimes, but all the time, the Lunkenheimer Valve works — not some- 

 times, but all the time. « 



Every AGMCO steam heating plant is equipped with Lunkenheimer valves. To be sure, the initial cost is more— but in the long 

 run, they cost less. 



YOU axe a practical man. YOU know valves, too. And YOU'VE had valve 



trouble, just when you've had no time to fool with it. 



Here's your chance to dodge that trouble.

Since the other house has only one

 ';nd has a length of but seventy-five

 ■inch flow should be able to maintain

use l^^-inch pipe for the return coil. So 

 far as I can judge from the data fur- 

 nished, the amount of radiation in the 

 different houses is correct and I would 

 not suggest any change in any of the 

 houses except putting in a 2yi>-inch 

 main to supply the short coil in the 

 wide house.
