What is the load line in control valve?
Answer / carl_ellis
A Load line shows the valve's pressure drop at different
flow rates. When graphed, the flow rate is typically on the
y axis, the pressure drop on the x axis.
Typically the load line starts high at low flow (high DP)
and decreases as the flow increases to a low DP when the
valve is wide open.
