For a knife gate valve used in 65 degrees Celsius and 54% phosphoric acid, what material should be chosen? The customer previously used 316L gate valves that were corroded; what material would be suitable? Thank you!
Thank you. The customer also wants a version with fluorinated lining, but the gate valve doesn’t have a gate component with fluorinated lining

The customer is currently installing knife gate valves, and only knife gate valves are accepted.
I have a friend who works in this field; you can add me on WeChat at 18721872815 and I’ll introduce them to you
Alloy steel grade 20 is fine; 00Cr20Ni35Mo3Tu4Nb is just too expensive
It should be available; it’s just expensive! It’s mainly corrosion
A 2205 duplex stainless steel valve disc can be used
