Data Sheet

Gases are used in chemical and industrial
processes, such as analytical instrumentation,
environmental compliance, electronic
manufacturing, chemical production,
reference gases, and medical uses. All the
devices in these systems must be compatible
to prevent complications, such as corrosion,
unwanted chemical reactions, ignition, or
explosion. Also, some of these process systems
operate at very high or very low temperatures.
Regulators must be constructed to withstand
these temperatures.
The regulators and relief/backpressure
regulators covered in this section are available
in materials that are chemically compatible
with most process gases. The products shown
in the Air, Liquids, and Sanitary sections may
also be used in your system if the materials
are compatible.
