Which expert knows what kind of valve this is?

The poster can take a few more photos. It looks like a high-pressure check valve

I guess I’ll have to ask the senior engineer. Also, it’s not clear in your picture what’s going in and out of the pipeline; at first glance, it might seem like a blind flange.

DN20, sealing surface RJ. The rest is indistinguishable

Based on its appearance, it can only be determined that it is a high-pressure valve; it’s not possible to tell what specific type it is. The original poster could please explain in what kind of pipeline it is used!

Check valve? Is there also a backflow preventer down there?
