5.2 Assembly of Spring-energized Seal Ring
These valves have spring-energized seal rings maintained expanding by a spring.
Installation of the high-pressure lip seal is like that of the standard lip seal with the exception that it requires additional force
due to the added stiffness of the seal. In addition to requiring more force, care must be taken not to damage the lip of the
seal during the installation. See Figures 5, 6, 7 and 8..
