Check valve slam, a problem commonly associated
with check valves, is often discovered during startup of
the pump system, by which time it is too late to easily
overcome. An extensive program of valve flow testing
conducted to develop profiles of slamming characteristics
for various types of check valves is described.
Research results led to a methodology designed to help
system designers predict and ultimately prevent check
valve slam through selection of valves that are less
prone to slam and associated water hammer.
Different check valves offer different advantages
such as reduced cost, low head loss, or special flow
characteristics. Ultimately, the best check valve is the
one that meets the requirements of a particular
installation or application. Consulting engineers and
utilities alike can use the data that are provided in
this article, combined with field experience and
other readily available information, to make
informed choices and resolve check valve
problems. Includes 5 references, table, figures.
