There are many process parameters that should be provided for the sizing of control valves. Here just examples of parts of the most important data
Generally, the terms rangeability and turndown ratio are associated with control valve sizing and flow measuring devices.
Theoretically dropping high pressure across two valves is better than one valve. However, in practice, two valves will not usually control well together unless the
Noise is created by an object vibrating. The control valve components will tend to vibrate whenever they are subjected to high-velocity turbulent flow.
Inherent characteristics are the flow through the valve (or CV) relative to the percentage opening (the pressure drop at both ends of the valve is
The most common features are shown in the figure above.The percentage of flow through the valve corresponds to the stem position.These curves are based on
The inherent flow characteristic of the control valve is the relationship between the flow and travel of the valve to a constant pressure drop across
The Venturi desuperheater adopts restrictive measures in the superheated steam pipeline to form a high-speed and turbulent area where cooling water is injected. This helps
In general, a vapour phase consists of a phase with two different substances at room temperature, whereas a gas phase consists of a single substance
