In general, diaphragm casings, diaphragm plates,
springs, and other parts not in the main flow stream
may be of ordinary materials such as carbon steel,
stainless steel, or cast iron. It is suggested, however,
that all valve body and trim parts in contact with the
flow stream be made of copper, copper alloy, or
nickel-copper alloys.
3. All diaphragms in contact with oxygen gas should
be made of fluoroelastomer.
4. All O-rings in contact with oxygen gas should be
made of fluoroelastomer or a similar fluorocarbon
elastomer.
5. Organic materials should be avoided for use in
valve seats or other parts exposed to the flow
stream.
6. Filters should be placed upstream of all valves
and regulators. Only non-ferrous, inorganic filter
elements should be used. Filters must have regular
maintenance and cleaning.
7. To minimize the number of parts in contact with
oxygen, oxygen should not be used as supply
pressure to a pneumatic instrument or an actuator.
8. Plated parts should not be used in the main flow
stream because of their potential contributions to
foreign particle impingement.
Note
Some users of oxygen valves and
regulators have established their own
standards and specifications for
construction materials. The
customer’s instructions in those
instances will be followed. Emerson
Process Management disclaims
responsibility or liability if materials
other than copper-based alloys or
nickel-copper alloys are in contact
with the flow stream.
Note
Neither Emerson, Emerson Process
Management, nor any of their affiliated
entities assumes responsibility for the
selection, use and maintenance of any
product. Responsibility for the
selection, use, and maintenance of any
product remains with the purchaser
