What is the best way to set the pressure of the safety and relief valves?

1. Adjust it manually

2. Find the name plate of the safety valve

3. Consult the owner

4. Use a pressure gauge

The correct answer is: Find the name plate of the safety valve

Finding the name plate of the safety valve is crucial because it provides the manufacturer's specifications regarding the set pressure of the safety and relief valves. This name plate typically indicates the maximum allowable working pressure (MAWP) and the set point for the relief valve, ensuring that the valve operates correctly within its designed parameters. Relying on the name plate ensures compliance with safety standards and prevention of potential overpressure situations, which can lead to equipment failure or safety hazards. In contrast, manually adjusting the pressure requires specific knowledge and experience and could lead to improper settings if these specifications are not understood. Consulting the owner may not provide the technical details necessary for adjusting pressure correctly, as they might not be aware of the critical specifications. Using a pressure gauge is important for monitoring but does not directly inform about the correct set point established by the manufacturer as documented on the name plate.
