Oxygen Service Ball Valves (O)
HABONIM ball valves for oxygen service are suited to be used with both liquid and gaseous
oxygen, cleaned and assembled with required measures for a safe use in oxygen service
equipment and avoid valve contamination to the media purity.
Note: Habonim oxygen service valves (O) are not following any medical-use or breathing
oxygen standards or regulations.
Oxygen
Oxygen, chemical element with symbol O2 , content in air is approximately 21% by volume.
Oxygen is an odorless, colorless gas, with many industrial uses, mainly in the manufacture of
steel and chemicals. Oxygen itself is nonflammable, however materials that are flammable in
air, burn far more vigorously mixed with oxygen. Oxygen is shipped as a non-liquefied gas at
pressures of 2000 psig (138bar) and above, also as a cryogenic liquid at pressures and
temperatures below 13.8bar (200 psi) and -146.5°C (-232°F). Air separation plants produce
pure oxygen via liquefaction of atmospheric air and separation of the oxygen by fractionation.
Also minute quantities of Oxygen can be produced by electrolysis of water.
Oxygen density is 1.429 kg/m3 (1.013bar at 0°C) Oxygen boiling point -182.95°C (-297.31
°F) at a pressure of 1 atmosphere, the liquid oxygen usually stored under high pressure or at
cryogenic temperature. Oxygen melting point -218.79°C (-361.82°F).
Oxygen Uses
Oxygen is used extensively in medicine, high altitude flying, deep sea diving and as rocket
fuel. Industrial applications include utilization with acetylene, propane, hydrogen and other
fuel gases for metal cutting, welding, hardening and scarfing. In steel and iron manufacturing,
oxygen helps increase the capacity and efficiency of furnaces. Another major use of oxygen is
in the making of 'Synthesis Gas' for production of gasoline, methanol and ammonia. Oxygen is
also used in the manufacture of nitric acid, ethylene and other compounds.
Oxygen Hazards
Oil, grease or other combustible substances should not be allowed to come in contact with
oxygen service valves or components. Oxygen combined with these substances can result
in explosions.
