True or False: A pressure reducing valve lowers steam pressure from 100 psi to 15 psi while maintaining the same heat level.

The assertion is true because a pressure reducing valve is specifically designed to lower the pressure of steam from a higher level to a lower level while ensuring that the temperature and heat level remain consistent. In this scenario, the valve takes steam at 100 psi and reduces it to 15 psi, effectively allowing for the control of steam pressure in various applications without significantly altering the thermal energy of the steam.

This capability is paramount for systems that require different pressures for effective operation while ensuring that the heat energy remains proportional to the desired application. It's important to note that while the valve can achieve the desired pressure reduction, any changes in heat levels would primarily depend on factors external to the pressure reducing valve itself, such as the steam's entry temperature and the heat transfer conditions within the system.
