** For comparison with filters and lubricators.

(0-4.1 bar) ranges, consult ROSS.

Precision Regulators have a small valve seat and a large diaphragm
area, a combination that allows greater precision, sensitivity, adjustment
resolution, and less variation in regulated pressure.

Relief Valves ha ve maximum relief flo ws of 10 to 20 scfm (4.7 to 9.4 l/s).
For models with increased sensitivity at lower pressure, consult ROSS.
