Does anyone know anything about special stop valves for hydrogen?

As the title suggests, I am in need of a special stop valve for hydrogen use; unfortunately, I can’t find any manufacturers that produce such valves. The material should be 304, with a DN15 size and flange connection. I wonder if anyone is aware of any suppliers. Thank you in advance
I’ve never heard of it; we all use ordinary carbon steel stop valves

Use Disk type – remember to use welding
Where are stop valves used? Ordinary pipes are made of carbon steel, and valves are also carbon steel gate valves; no special types of valves are used – just ordinary shut-off valves. Or are you referring to safety shut-off valves?
Sorry, I got the first shut-off valve wrong; it’s a gate valve!
