Norgren 20AG User Manual

11-002 & 20AG
Pressure Regulator

1/4", 3/8", and 1/2", G3/4, and G1 ports

Large diaphragm provides accurate
and quick response to changing flow
demands and line pressure

Floating valve pin provides positive
valve seating

Balanced valve minimizes effect of
variations in inlet pressure on outlet
pressure

Standard relieving models allow
reduction of downstream pressure
when the system is
dead-ended
