Angle Control Valves Characteristics


The Inherent flow characteristic of a control valve is the relationship between the flow and the lift of the plug at a constant pressure drop.

The characteristic normally available, are shown.

Linear - Flow is directly proportional to valve lift.

Equal % - Flow changes by a constant percentage of its instantaneous value for each unit of valve lift.

Quick opening - Flow increases rapidly with initial travel reaching near its maximum at a low lift.
