Medium for transporting dilute hydrochloric acid. Are PTFE or EPDM valve bodies generally used?

The valve body is made of PTFE, and the diaphragm is made of EPDM.

Come and learn*; I’ve never used a diaphragm valve before

Personally, I think something corrosion-resistant should be used, such as PTFE

I just started and don’t understand it; I’ll learn it!*

For a carbon steel valve body lined with a natural rubber diaphragm, EPDM should work just fine.
