Any process flow through piping and control valves is almost always considered as turbulent. The reason being the process has to go through so many

The critical pressure is the vapor pressure of a fluid at the critical temperature above which distinct liquid and gas phases do not exist. As

The internal parts of the valve body, valve stem, valve seat, packing set, valve plug, gasket, etc. are collectively referred to as valve trim. In

A choke valve is a type of control valve that has a restriction orifice that is used in oil and gas production wells to control

Incipient cavitation represents the beginning stage of cavitation where light popping noises are heard. Constant cavitation is a steady rumbling sound associated with the start

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
