It's been awhile, but Consolidated Valve used to have some excelent material on safety valves including colored cut aways... (are they still around?)

Consolidated and Anderson Greenwood are now the same company, can't say who bought who.

This could be of help.

http://www.nationalboard.org has info on a Pressure Relief Valve Seminar which can be helpful.  There is one scheduled for July 28 to Aug 1, 2003 and another in October, 6 thru 10, in Columbus, OH.

Our organization presents On Site Hands-On Training Seminars on Pressure Relief Valve Repair.  If you are interested, you may want to visit our website at http://www.delucatest.com.  We conduct classes for Nuclear Utilities, Pharmaceutical Plants, Oil Refineries and PetroChemical Facilities worldwide.

Not that important perhaps, but I'm pretty sure that Crosby is with Anderson Greenwood, and that Consolidated is with Dresser.
