Control Valve Plug Characteristics at Martin Horvath blog

Control Valve Plug Characteristics. When valves are installed with pumps, piping and fittings, and other process equipment, the pressure drop across the valve will vary as the plug moves through its travel. The control valve characteristic curve or inherent characteristic determines to a considerable degree the attainable control accuracy and. However, the design of the shape of a control valve and its shape. The shape of the plug primarily decides the flow characteristics. 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 valve. Each valve has a flow characteristic, which describes the relationship between the flow rate and valve travel. Control valve trim is manufactured in a variety of different “characteristics” to provide the desired installed behavior. The plug position responds to. As a valve opens, the flow characteristic, which is inherent to the design of the selected valve, allows a certain amount of flow through the valve at a particular percentage of the stroke. The flow characteristic of a valve is normally defined in terms of (i) inherent or ideal characteristics and (ii) effective or installed characteristics.
