Course Outline

A safety or pressure relief valve can be considered the most important single safety
device on a boiler or pressure vessel. If it fails to function in the manner for which it is intended and an overpressure condition develops, the result could be catastrophic.

Like all mechanical devices, pressure relief valves require periodic maintenance and repair. To properly carry out repairs, it is essential that the work be done by trained personnel under controlled conditions, using proper parts and procedures.

This State-of-the-Art course is developed in keeping with the American “National
Board of Boiler and Pressure Vessel Inspectors”. The National Board of Boiler
and Pressure Vessel Inspectors’ Executive Committee, realizing the importance of
proper and adequate repair of safety relief valves, approved the issuance of a
National Board Certificate of Authorization for Valve Repair and a “VR” stamp
to qualified organizations. Such organizations are required to maintain a quality
control system covering valve repairs and be able to adequately demonstrate this
system.

In addition, a committee was formed to develop administrative procedures
and rules for the repair of valves. This committee recommended a course on valve repair to help ensure that those who carry out this work are capable and
knowledgeable. Hence, don’t blow off this chance to learn the latest information on
pressure relief systems.

The first four days of the course consists of valuable lectures on Safety Relief
Valves. The last day (Day 5) will be a practical/ overview training in a workshop
environment, where participants will witness Testing of the valve types that
were Disassembled, Inspected and Assembled in class during the week.
The course covers the conventional spring loaded Pressure Relief Valves (PRV)
and the Pilot Operated Pressure Relief Valves (POPRV).
