What is the difference between Pressure ๐‘๐ž๐ฅ๐ข๐ž๐Ÿ ๐•๐š๐ฅ๐ฏ๐žand Pressure ๐’๐š๐Ÿ๐ž๐ญ๐ฒ ๐•๐š๐ฅ๐ฏ๐ž

You see these devices on tanks, pipelines, and boilers. Many engineers just call them โ€œsafety valves.โ€ But thereโ€™s a big difference, and knowing it can prevent equipment damage or worse, a plant incident.
