Background

Valves are mechanical devices that control the flow, direction, pressure, temperature, etc. of a flowing fluid medium, and are essential components in a piping system. Valve tubing, like pumps in technology, is often discussed as a separate category. The valve can be operated manually or by a hand wheel, a handle or a pedal, and the pressure, the temperature and the flow rate of the fluid medium can be changed by control. The valve may operate continuously or repeatedly on these changes, such as a safety valve installed in a hot water system or a steam boiler. In more complex control systems, automatic control valves are employed as required by external inputs (i.e., to adjust the changing set point of the flow through the pipe). The automatic control valve does not need manual operation and can accurately control various requirements of fluid medium according to the input and the setting of the automatic control valve.
