R Series
Spring-Loaded Pressure Reducing Regulators
Tartarini TARTARINI Emerson
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.
The R Series regulators achieve high
accuracy and flow rates even with
low inlet pressure and inlet pressure
variations.
