Fuel Gas
Natural gas (methane) is a clean-burning fuel
gas used for many residential, commercial, and
industrial applications. This colorless, naturally
occurring gas can be found in many countries
around the world.
For industrial applications, natural gas is used
as a feedstock for making chemicals, such as
anhydrous ammonia, and as a fuel for boilers
and furnaces.

Bulletin No. 71.1:Y600A
Y600A Series direct-operated, spring-loaded regulators provide economical pressure-
reducing control for a variety of residential, commercial, and industrial applications.
The large diaphragm area provides more accurate control at low-pressure settings.
The pitot tube of regulators also creates a dynamic boost that helps provide
greater capacity.
