What is the primary purpose of valves in a steam system?

The primary purpose of valves in a steam system is to control the flow of steam and water. Valves serve as critical components that regulate the movement and direction of fluids, allowing operators to manage processes effectively. In steam systems, this includes controlling the supply of steam to turbines, boilers, and heating systems, as well as regulating the discharge of condensate and water to maintain optimal operating conditions.

By adjusting the position of the valves, operators can ensure that the correct amount of steam or water flows through the system according to demand and maintain efficiency. This flow control is crucial since it directly impacts the performance, safety, and reliability of the steam system.

Although other functions mentioned, like enhancing fuel combustion or maintaining pressure, are important in their own right, they are not the primary role of valves. Valves are fundamental for directing fluid flow rather than affecting how fuel burns or ensuring pressure levels.
