how can check the loopchecking for valves?

Answer Posted / gnb

First I have explain about Loop Check. Loop check means
that we have to check the functionality of Field
Instruments to DCS/PLC.

For Valves,you have to simulate the value from DCS/PLC in
step by step(0%,25%,50%,75% and 100%).Valve actuation to be
confirmed by actuator Scale which is in the Valve.
