Re: regular bore valves

You would also want a full-bore valve to minimize potential entrapment of contaminants (say, HC in O2 flow) and for flows that contain solids (for example, pulp or other semi-solids). Both full-bore flow options would reduce downtime between cleaning/purge-derime.

But then, I'm not a valve expert.
