Note: 224486 and 223824 LS BPR 1000 provides optimum protection of sheer sensitive coatings.
Note: 903508 includes 208997 plus gauge 208855 and bushing 501918.
Note: For material viscosities less than 5 centipoise, regulator should be tested by customer before making multiple regulator installations.
Very low viscosities regulation at low pressure may not be possible.

Back Pressure Regulators for Medium/High Pressure
Maintain proper flow rate at medium to high pressures.
