Pressure Relief Valves

In general, the term “safety valves” and “pressure relief valve” are used interchangeably

The shape and the work done in both types of valve are the same, which is to limit the amount of pressure of a liquid, vapor or gas by discharging part of that fluid.

he characteristic of these valves is their quick opening and closing. Pressure relief valves are commonly used for liquids and are either open or closed at high or low pressure and slowly.
