What are the different valve characteristic ?
The different types of valve characteristic are : 1. Linear 2. Equal Percentage 3. Quick Opening.
1.Linear: The valve opening to flow rate is a linear curve 2.Equal percentage: For equal increments of valve opening it will give equal increment in flow rate range. At small opening the flow will also be small. 3.Quick opening: At small opening the increments in flow rate is more. At higher opening the flow rate becomes steady.
