This document contains specifications for a steam flow system for a customer in Mexico. It provides key parameters for the steam and water flow including temperature, pressure, flow rates, and velocities at minimum, normal and design conditions. It also lists the expected sound pressure level drop and stem forces needed for the control valve. The nearest standard configuration is selected along with specifying the use of stellite nozzles for the valve.
