Question: 1 / 400

At what pressure is a pressure relief valve on a tank typically set?

200 PSIG

250 PSIG

The pressure relief valve on a tank is typically set at a predetermined pressure level to ensure safety and prevent overpressure conditions. The setting often takes into account the design pressure of the tank and the specific application it is used for.

In this context, 250 PSIG is a common and standard pressure setting for many industrial and commercial applications. This value is generally selected to provide a sufficient safety margin above the normal operating pressure, ensuring the relief valve activates before reaching potentially hazardous levels of pressure that could compromise the integrity of the tank.

Other options, such as 200 PSIG, 300 PSIG, and 350 PSIG, may be applicable in certain contexts or industries but are not the most commonly used settings for standard pressure relief applications. It’s important to refer to the specific requirements and safety codes relevant to the equipment being used when determining the appropriate set pressure for a pressure relief valve.
