Valve Characteristics – Quick Opening, Linear & Equal Percentage

In essence a valve simply functions as a restriction in a flow line, with flow areas A1 and A2 and pressure

Each valve has a flow characteristic, which describes the relationship between the flow rate and valve travel. As a valve

The flow regulation in a valve is accomplished by the varying resistance as the valve is stroked, i.e. its effective

All control valves have an inherent flow characteristics that defines the relationship between ‘valve opening’ and flowrate under constant pressure
