Noncompensated flow controls are simple valves that meter flow by restricting or throttling. The amount of flow that passes through an orifice and the pressure drop across it are directly related.

Process control valve flow characteristics make regular loop tuning a necessity. Understanding the basics can ease the frustration and ensure loop stability. But first, some basics about why this ...

Connell Method. In this method, the minimum pressure drop assigned to the control valve is based on pump discharge pressure, increased frictional pressure drop due to maximum flow rate ...

Choked flow in control valves is a subject of serious concern for industrial users. The term is usually associated with destructive process conditions that can damage valve internals or expose ...
