Control Valves Mechanical Friction Problems

Control valves are mechanical devices with moving parts, and as such they are subject to friction, primarily between the valve

Both gas and liquid control valves may experience what is generally known as choked flow. Simply put, “choked flow” is

Calibration refers to the adjustment of an instrument so its output accurately corresponds to its input throughout a specified range.

The flow capacity of a valve (Cv) is a quantitative rating of its ability to pass a fluid flow for

Sizing a control valve for gas or vapor service is more complicated than for liquid service, due to the compressibility

Here we discuss about instrumentation related to industrial process safety. Instrumentation safety may be broadly divided into two categories: how

Any physical location in an industrial facility harboring the potential of explosion due to the presence of flammable process matter

What is inherent characteristic of a valve ? The inherent characteristic of a valve is the characteristic published by the manufacturer,

Now let us consider a scenario where the pressure drop across the valve changes as the rate of flow through

First, let us imagine a control valve installed at the base of a dam, releasing water from the reservoir. Given
