Application
The RG20 is a direct spring operated, pressure
regulator that can be used anywhere pressure
regulation of natural gas, air or other gas is required.
It’s housing can be moved to one of four positions to
save space during installation.
The RG20 was designed for easy maintenance by
allowing access to the body without removing it from
the line. A NACE option is available for sour service.
Model RG20 Installation
Installation
Before installing the RG20, check the condition of the
threads to make sure they’re clean and clear of
debris. Use pipe thread compound to ensure no
pressure leaks from the connection and thread it onto
the pipe. The RG20 has the capability to change the
position of the housing four different ways to save
space during installation.
WARNING: The RG20 is not a self-relieving regulator.
If there is a chance that the outlet pressure could rise
above the set point the excess pressure will cause
damage to the regulator. It is recommended to use
some type of pressure relief device on the
downstream side of the RG20 to prevent this.
