I’m sorry; I only have the old samples available. As far as I know, the Q41 ball valve has a flange connection and can handle a pressure of 2.5 MPa. I would like to ask everyone: are there any ball valves with a DN20 size, a pressure rating of >Pn4.0, made of stainless steel, and manual operation – without automatic control?

"Are there ball valves that don’t operate automatically? Do they need to be operated manually? Yes, there are such ball valves that require manual operation!

This valve is used for unloading; the dn of the unloading valve is >50 and the pressure is also low. What valves are available?
