Which will not be found on a safety valve's nameplate?

The nameplate of a safety valve typically includes essential information that allows operators to understand its specifications and performance characteristics. One essential characteristic found on a safety valve's nameplate is the ASME stamp, which signifies that the valve complies with the American Society of Mechanical Engineers' standards for safety and reliability. This symbol is crucial for compliance with safety regulations and industry standards.

The capacity, which indicates the maximum flow rate that the valve can handle safely, is also included. This information is vital for ensuring that the safety valve operates correctly in the context of the system it serves so that it can discharge the necessary flow in case of overpressure.

Another important piece of information commonly found on a safety valve's nameplate is the blow down rate. This rate indicates the difference in pressure between the set pressure and the reseat pressure, giving operators an idea of how quickly the valve closes after it has opened due to overpressure conditions.

In contrast, temperature settings are generally not specified on a safety valve’s nameplate, as safety valves primarily deal with pressure relief and not temperature control. Temperature considerations may be part of the overall system operation but are typically not a standard specification listed on the valve's nameplate. Therefore, this is the correct choice for what will not be
