Valve Characteristics – Quick Opening, Linear & Equal Percentage

S Bharadwaj Reddy
In essence a valve simply functions as a restriction in a flow line, with flow areas A1 and A2 and pressure differential p1 – p2, as shown in Below Figure. Valve Characteristics

Difference between Quick Opening, Linear & Equal Percentage Control Valve characteristics

S Bharadwaj Reddy
Each valve has a flow characteristic, which describes the relationship between the flow rate and valve travel. As a valve opens, the flow characteristic, which is inherent to the design

Control Valves Theory

S Bharadwaj Reddy
The flow regulation  in a valve  is accomplished  by the varying  resistance as the valve  is stroked, i.e. its effective cross sectional area is changed. As the fluid moves from

Control Valve Characteristics

S Bharadwaj Reddy
All control valves have an inherent flow characteristics that defines the relationship between ‘valve opening’ and flowrate under constant pressure conditions. Please note that ‘valve opening’ in this context refers
