Answer Posted / ravi sankar
we can calibrate the control valve by using source meter
which is used to give 4 to 20 ma source to I/P , if any
error in the I/P ,we can adjust the zero or span of I/P.if
any error in the valve position ,adjust the zero or span in
the posisner of the control valve.

Calculate the maximum pressure drop that can be allowed to occur across a control valve, so that we can prevent cavitation / flashing from occurring. Use the following formula: Δ P allow = Km (P1 – PvapourA) where, Δ P allow - the maximum allowable differential pressure for sizing purposes, or terminal pressure drop; Km- the valve recovery coefficient from the manufacturer’s catalogue; P1 - absolute inlet fluid pressure; PvapourA - absolute fluid vapour pressure at the inlet temperature; Use Atmospheric pressure = 101.3 kPa, P1 = 1200 kPa(g), PvapourA = 4 kPa, KM = 0.72
