Pressure Relief Safety Valves

Pressure Relief Safety Valves

Pressure relief safety valves.

Pressure is measured in "bar". One bar is about equal to the atmospheric pressure on Earth at sea level. In "old money" it's equal to 14.5 pounds per square inch (PSI).

The outlet from a pressure relief valve should be positioned in a way so as to not scald people or animals with escaping hot water or steam.
