dear,
sometimes it is required to run a centrifugal pump after starting it against a closed valve to ensure that the proper pressure is built up and then open the motorized valve.
Do we usually include a pressure transmitter before the motorized valve to ensure that proper pressure is built up and then use the measured pressure value to open the motorized valve or open the motorized valve after a predefined time?
any thought is really appreciated.
thank you!
