what is the difference between servo valve & proportional
valve
Answer / prashant sharma
A servomechanism, usually shortened to just servo, is a
device used to provide mechanical control at a distance.A
servo can be used at a remote location to proportionally
follow the angular position of a control knob. The
connection between the two is not mechanical, but
electrical or wireless.Servos are commonly electrical or
partially electronic in nature, using an electric motor as
the primary means of creating mechanical force, though
other types that use hydraulics, pneumatics or magnetic
principles are available.
A proportioning valve is a valve
that relies on the laws of fluid pressure to distribute
input forces to one or more output lines. A proportioning
valve can increase or decrease forces for each output,
depending on the cross-sectional surface areas of those
output lines.

On LPG sphere tank we used LIT for level indication.High side port is connected to the bottom of the tank while low side port connected to the top. I would like to know how to fill the glycerin on its low side with two condensing pot installed,one from top and the other one for its drain line.Please I need your expertise...thanks
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.
