Home / Learn about steam / Safety valves

This section answers the questions: what is a safety valve, what options are available, and how to choose the right one, and safely install it.

Safety Valves

Safety valves are essential devices used to protect from steam overpressure. Here we look at how this might happen, the range of types available, how they work, and the regulatory frameworks for them.

Types of Safety Valve

Discover in detail the many variations of safety valves, how they operate (including equations illustrating the force needed to do so), and diagrams of each type of valve.

Safety Valve Selection

Including the criteria you will need to consider, how safety valves are properly installed, and where, and the difference between MAWP and MAAP.

Safety Valve Sizing

A detailed look at how to size valves according to various standards, with diagrams and equations for each case. We also look at more complicated solutions like two-phase flow and superheat.

Safety Valve Installation

For it to work correctly, it's vital you know all the factors to make the right decision. Everything you need to know is covered here.

Alternative Plant Protection Devices and Terminology

They might be the most effective, but safety valves are not the only way you can deal with excess pressure. This section looks at the alternatives and gives a full glossary of terms related to this topic.
