Types of Relief Valves and how will you Calculate it’s Size

Question

Accepted Answer

Relief valves are of two types - pressure relief valves and safety relief valves. Their size is calculated based on the flow rate and pressure.

Pressure relief valves are used to protect equipment from overpressure and are typically set at a specific pressure level.
Safety relief valves are used as a last line of defense and are typically set at a higher pressure level than pressure relief valves.
The size of a relief valve is calculated based on the flow rate and pressure that it needs to handle.
The American Society of Mechanical Engineers (ASME) provides guidelines for sizing relief valves.
Factors such as the type of fluid, temperature, and operating conditions also need to be considered when sizing relief valves.
