Pressure relief valve safety considerations during design

Click For Summary
SUMMARY

The main safety considerations during the design of a pressure relief valve (PRV) include adherence to industry standards, correct orifice diameter, and accurate minimum system pressure settings. Diagnosing incorrect designs involves verifying orifice size against established standards and assessing system functionality under varying pressure conditions. An incorrect system pressure at the minimum setting can lead to malfunction, potentially compromising safety. Understanding the application and circuit for the PRV is crucial for effective design and troubleshooting.

PREREQUISITES
  • Knowledge of industry standards for pressure relief valves

What are the main safety considerations during design of a pressure relief valve? and how would you go about diagnosing if they are incorrect?

Is the following correct?

Orifice diameter for a fixed pressure - How to diagnose if it wasn't correct?

What effect would a incorrect system pressure at minimum setting have? Would the system just not function?

Thanks,

You should design the PRV to an industry standard. You can also verify the that the orifice is the correct size with the same standard.

My first question is why are you designing a relief valve as opposed to purchasing it off-the-shelf? Second, what is the application? Third, what is the circuit that the relief valve is to be used?

Then we can start giving you some good information. There are a few of us here who can help you.
