I would appreciate it if experts could analyze, from the designer’s perspective, why such arrangements were made and what the function of each valve is. (Image 1 shows the inlet for glycol-rich fluid, while Image 2 shows the outlet for heat transfer oil.) In Figure 3, there are two safety valves – one in use and one as a backup – along with a bypass valve; however, there are many differences in the details, especially regarding those 3/4” ball valves. I would appreciate it if experts could explain why this arrangement is used and what the function of each valve is. (Image 4 shows the inlet for glycol-rich fluid, while Figure 3 shows the inlet for heat transfer oil.)
Please zoom in on each image before posting it, label them as Figure 1-4; even if you ask someone for help, don’t go to such lengths. . .
It’s indeed too small; a click is required. The bypass for the safety valve is the normal discharge bypass, while the quarter-size valve is the drain valve, which is used during maintenance
