Two systems are at different pressure 8 barg and 2 barg. Two systems are separated with a block valve (diaphragm valve manual) PN16 same as the piping system (10 barg @ 120 C)
I got a question: the pressure difference is too much, diaphragm valve is not good enough. In my opinion, as long as the valve is PN 16, it should be able to take 10 barg @ right temperature. The pressure difference is not a issue. But I didn't find information regarding to question.
Hope someone can help.
Thanks in advance.
