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