Introduction
This manual has been prepared to
serve as a guide for the maintenance
of Edward valves of the pressure-seal
bonnet joint construction. It is
designed to help you obtain the most
satisfactory service from these valves.
Although rigid metallurgical, radi-
ographic, physical, and visual inspec-
tion is the standard procedure for all
Edward products, it is inevitable that
some valves, after a period of time,
may occasionally require repair.
When this happens, this manual will
assist you so that your valve may be
satisfactorily restored to good work-
ing condition with a minimum of time
and expense.
Scope
Before starting, it will be helpful to
have some understanding of the
valve’s physical construction. Con-
sequently, the four basic types of
pressure-seal constructions are dis-
cussed and illustrated first. All Edward
pressure-seal valves employ one of
these four basic types, or a minor
modification thereof. Non-pressure-
seal, or bolted bonnet type valves,
are not included in this manual.
The next major section of this manual
discusses the more common service
problems and failures. It identifies the
problem and explains the reasons for
certain failures. The reason should
be understood before work is
actually started.
