RE: Select flanged ballvalve type in oxygen service?

Depends on your pressure.  In some services, quarter turn valves of ANY kind are prohibited due to the risk of adiabatic compression leading to a fire.

RE: Select flanged ballvalve type in oxygen service?

I agree with moltenmetal.  The use of ball valves in oxygen service should be discouraged if not prohibited.  Our company prohibits them, and I work for one of the major industrial gas companies.
