A Word About Cryogenics...
Cryogenics, the science of materials at extremely low temperatures, has become more and more
important to industry. One important aspect of this field is the liquefaction of normally gaseous elements,
including the following, which are widely used throughout industry:

OXYGEN - Used extensively in BOF furnaces in the steel industry, for metal cutting, as a rocket fuel and in
medicine.

ACETYLENE - Widely used in welding.

NITROGEN - Used in refrigeration systems, for metal degassing, in aerosol packaging and in cryogenic
surgery.

HYDROGEN - Used as a rocket propellant and in the production of several metals.

ARGON - Widely used in incandescent lamps and fluorescent tubes.

HELIUM - Used for arc welding, in the manufacture of electron tubes and in cryogenic research.

CARBON DIOXIDE - Used in refrigeration, to make aerosol tanks and in fire fighting.

Other cryogenic fluids include liquefied natural gas, fluorine, krypton, neon, methane and ethane.
Cash-Acme has an extensive line of cryogenic valves and controls. Includes pressure reducing valves,
pressure build-up regulators, back pressure valves, economizer valves, combination valves, low
temperature cut-off valves, safety relief valves, shut-off valves, final line regulators, strainers and high
purity valves. Full specifications of construction, dimensions and available pressure ranges are contained
in separate bulletins.
