Since the Pressure Relief Valve was invented there has been a need for valve sizing
and selection. Over the years there have been a wide variety of ways to size a valve.
In the beginning engineers would use their abacus, pencil and paper to size a valve. Ok,
maybe the abacus is a little far fetched. However it was a labor intensive process that
individual engineers would manually perform. Over the years calculators improved how
users would size a valve. Eventually catalogs were published with a calculator strip that
could be fed into your HP calculator that would size your valve for you.
In today's world we have evolved so quickly with technology, there are lots of
options for sizing and selection tools. It seems logical that custom developed applications
have been one of the most popular methods for sizing a vendors product. Excel spreadsheets
are also a very popular method. Over the years at Tyco there have been a series of different
valve sizing programs. Below is a list of different sizing programs that have been developed and
in some cases they are still in use today.
