Introduction
The R Series spring-loaded regulators
provide pressure reducing control for
domestic and industrial use, such as
burners, furnaces, boilers and other
installations requiring proper regulation
and quick response time.
These regulators can be used with non-
corrosive gases, such as natural gas,
compressed air and nitrogen.
The R Series regulators achieve high
accuracy and fow rates even with
low inlet pressure and inlet pressure
variations.
