Valves
Valves and its application
Valves are mechanical devices that control the flow and pressure of liquids, gases, and slurries within a system. They are also known as regulators and are used in a wide variety of applications. Valves vary greatly in size, design, function, and operation. There are several methods that can be used to classify valves including the control mechanism and valve function.
