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.

when the operation engineer told you that he gives the control valve order to open but there is no response ! what will you do ? and if you found that there is astuck , what will you do ? (note : it is apanumatic valve )

We Have Two Field bus Pressure Transmitters of Different Sensor Range (I.E One is of Lower range and Another is of Higher Range).Is same Process Line. My Question is Can i provide Saturation Limit to my field Bus Transmitter as We can provide Saturation current limit to HART Instruments. As During Low Pressure Both Working OK ,But During High Pressure, transmitter with Lower sensor range Goes to Fault mode as Beyond its Sensor Limit it can Measure, So may I provide Saturation point Some where to Suppress This Fault during High Pressure.
