Where should you check for the maximum setting of a safety and relief valve?

The maximum setting of a safety and relief valve can be found on the nameplate of the valve. This nameplate provides essential information about the valve, including its maximum allowable pressure setting, temperature limits, and manufacturer details. It is crucial for ensuring that the safety valve operates correctly within the designed parameters to prevent overpressure situations that could lead to failures or accidents.

While the user manual may contain general information about the valve, the specific settings are directly indicated on the nameplate, making it the most reliable source for the valve's specific maximum pressure limit. The pressure gauge and the installation site do not provide this particular information, as they are not directly linked to the settings established by the manufacturer. Checking the nameplate is the most accurate method to verify the maximum operational criteria for safety and relief valves.
