There are various kinds of pressure valves. Perhaps the 2 most common in homes are the PRV (pressure regulating valve) which is on most incoming water pipes from a city supply. This valve limits the pressure entering the home system, bringing it down from city mains pressure. The second is on every hot water tank, and this is a relief valve, which will open up if the pressure in the tank becomes too high and vent the excess water down the drain.

Difference between set pressure and blow-off pressure?

The set pressure is the pressure at which a relief valve starts to open. When the valve is open and relieving, the pressure will be higher or lower than the set pressure, depending on the system and the valve design. That is the blow-off pressure.
