Please let us know the stream conditions of MSTR-004 and what is expected as output stream conditions for MSTR-015? Or otherwise please share the file with us at contact-dwsim@fossee.in.

Thanks for replying.

It seems that I can only attach pictures. The pic attached shows a slightly changed process but the conditions at the material streams up and downsteam the valve are the same

thanks

You can try adding another flash algorithm (Nested Loops VLE), associating it with the valve.

I tried all flashing algorithms, but it seems that the valve cannot manage the presence of liquids

create a topic on the official forums, you can attach the simulation file there.
