27-Jun-14 we replaced the new control valve 071K00301 (CV12) but it did not work properly then the old valve (CV7.5) was taken back at that time.
However after the old valve (CV7.5) was installed back, its opening percent has been higher than before.
Today the new control valve 071K00301 (CV20) is installed. It opens at 100% to make pressure around 5.0 to 5.2 barg (SP is 5.3 barg)
Pressure transmitter 071P00301 should be re-calibrated even though it is exist and we don’t touch it.
I would like to ensure this pressure transmitter works properly.
Please issue notification and temporary bypass, thank you in advance krab.
