It is indicated on the drawing that, except for the different flow characteristic of the first one, everything else is the same
It’s the control valve, right? Does the quick-close valve have a valve disc?
Well, it’s to regulate the valve – how does it work? It seems to be 3, 1, 5, 2, 4! I only know about the 5th one, which is in the middle.
At startup of the 5 valve discs A, B, C, D, E: C, B, D, A, E are activated in sequence.
The 5 valves overlap with each other; the gap between the valves in the middle is approximately 50, while the gaps on the sides are around 3. They operate one after another
Start with the two sides first, add one in the middle last, to serve a regulating purpose
