Explain about Linear Control Valve Characteristics

Linear Control Valve Characteristics provides a linear relationship between the valve position and the flowrate.

The flow through a linear valve varies directly with the position of the valve stem.

This flowtravel relationship, if plotted on rectilinear coordinates, approximates a straight line, thereby giving equal volume changes for equal lift changes regardless of percent of valve opening.

These valves are often used for liquid level control and certain flow control operations requiring constant gain.
