Cantilever V-Spring
A helical spring is made by winding a thin, flat strip of metal into a helix, creating a round tube. Helical has a very steep load curve and offers the highest force per linear inch.
It's most often used in static face seal applications and in cryogenics where high loading is needed. It can be yielded after being compressed so it's usually not recommended for dynamic applications.
Why Use a Spring Energized Seal?
With many options available for Elastomeric U-Cups and O-Ring Energized Seals available on the market, why would you need a Spring Energized Seal?
A PTFE spring energized seal offers the greatest temperature range possible for a seal. They can be used in cryogenic applications approaching absolute zero all the way to combustion processes at 550°F. No elastomer will function at these temperature extremes.
With a PTFE and stainless-steel spring, chemical compatibility is also maximized. Applications with caustic or aggressive media may not be able to use any type of elastomer.
The shelf-life of a PTFE spring seal is also indefinite. SPT has employed spring energized seals in Dam Spillway gates that require 50+ years of service life.
Even in applications with benign media and temperatures, spring seals can still offer an advantage. Yes, you can energize a PTFE jacket with an O-Ring. But the load curve of an O-Ring is very undesirable, especially in rotary applications. A rotary seal using a canted coil will outperform an O-Ring in terms of friction, consistency, and wear-life.
Scraping viscous media such as epoxy resins? Multiple V-Springs inside a filled UHMW-PE jacket can provide optimum sealing and wear-life performance. With redundant sealing points and highly focused load, spring energized seal can do the job no other seal can.
