Conclusion
It is important to recognize that many parameters
affect seal performance and service life. Even if the
optimum design is selected, other factors such as stem
finish, packing bore finish, and job site installation
practices will have an effect on performance.
Emerson Process Management knowledge gained, as a
result of the ENVIRO-SEAL and HIGH-SEAL packing
development program, has provided an opportunity to
help you “engineer” the packing selection. Proper
selection has a bottom line result; that is, increased
service life and reduced maintenance.
If you need a more detailed engineering discussion of
the design principles affecting packing seal design,
contact your Emerson Process Management sales
office. They can provide you a copy of Technical
Monograph TM-38, Control Valve Packing Systems.
