Valve Fundamentals
Edward Brunet, Jr., P.E.
Overview
Valves are used to regulate
the flow of fluids in piping systems. They are used to throttle flow,
shut-off flow, reduce pressure, relieve pressure and prevent backflow.
Valves are one of the simplest components in most piping systems, but the
importance of proper valve selection cannot be overemphasized. Premature
valve failure can result in loss of fluid pressure containment, which often
leads to undesirable consequences. Before attempting to select a valve,
the engineer should first gain a basic understanding of each type of valve and
how it operates.
This course covers the
fundamentals of valves, including the different types of valves commercially
available and how they operate. The course material covers Module 4 -
"Valves" in the DOE Mechanical Science Fundamentals Handbook, which is an
excellent source of information in the Engineering Sciences.
The student must take a
multiple-choice quiz consisting of twenty-five questions at the end of
this course to obtain PDH credits.
