General
Oxygen Service feature is available for part of Habonim’s valves series – check series ordering
codes for availability. Available valve sizes, types and variety of end connections are per each
relevant series ordering codes.
Valve Component Materials
Gaseous oxygen is non corrosive and may be contained in systems constructed of any common
metal. Stainless steel, Monel, Bronze and Brass are sometimes the preferred materials for metal
components coming into contact with gaseous Oxygen. In the extreme low temperatures of
cryogenic liquid oxygen, stainless steel of 3xx series is often the preferred material. TFM, PTFE
or glass filled PTFE are inert in oxygen and are considered standard seat and seal materials for
oxygen service.
Warning! Delrin (Acetal resin) seats and Nylatron stem thrust seals MUST NOT BE USED IN
OXYGEN SERVICE.
Habonim oxygen service valves may be used with both liquid and gaseous oxygen. For
temperatures below -60°C (-76°F), we recommend using Habonim's Cryogenic valves series.
Cleaning, Assembling and Packing
A meticulous cleaning and assembly procedure minimize the ignition hazards that can be
caused by the presence of hydrocarbon oil, grease, and metal chips.
Our process of cleaning, assembling and packing refers to international standards in partial
or in full:
ASTM A380 | CGA G 4.1 | EN 12300
Habonim uses an environment friendly, alkaline-based degreasing process with controlled
parameters. Valves are assembled in an oil-free restricted area by personnel who are specially
equipped and trained to perform this task. The assembling area, work surfaces, equipment
and tools are specially maintained to ensure cleanliness requirements are met.
• Valves are capped ends and plastic bagged
• Each valve is packed with a 'Silica-gel pack'
• A sticker on the plastic bag indicating “oxygen use"
Optional Accessories
Locking Device (LD)
As a safety measure, it is advisable that valve for oxygen service should
be equipped with spring loaded locking device do avoid unauthorized or
unintentional valve operation.
