ENTECH CONTROLS
The Inherent ow characteristic of a control valve is the relationship between the ow and the lift of the plug at constant pressure drop. The characteristic normally available are shown as below.
LINEAR Flow is directly proportional to valve lift.
EQUAL% Flow change 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.
