In abnormally hot, dirty, or corrosive conditions, most 
shutoff  valves can deteriorate and fail to shut off  tightly. 
Frequent, periodic checking of all valves is recommended.

Threaded ball valves are designed for industrial, residential and 
commercial use on steam, water, oil or gas. Their full ports allow 
for maximum fl ow with minimum pressure drop and  turbulence. 
The valve is UL listed, FM approved, and the brass bodies are 
CGA 3.16 certifi ed. 

1821B ball valves can be ordered with the option to be cleaned 
for oxygen service. A locking handle option is also available.
