Hello every body
This is my first post in eng-tips.

I'm working in a new seal for butterfly valves and I need to find a supplier of plate springs (see photo)

They are commonly used in lipseals for criogenic aplications.
Any idea of who can produce this ?

Thank-youuuuuuuuuuuuu

In this case the material is elgiloy but can be inconel stainless steel or metals for cryogenic aplications.

If I understand your description and the photo properly, this is a garter spring made with rectangular wire/strip instead of round wire. Associated Spring can make just about any type of spring, and they are extremely competent in technically challenging designs, materials, etc.

These are usually custom designed springs for lip seals such as made by Balseal or Omniseal, etc. If you need exactly the same spring then the best is to find the seal manufacturer and purchase the spring. If you need similar spring then there are many other springs that will do the same work. For example Balseal patented slanted coils spring and others.
