摘要

Fluid flow control system has a control valve (22) for adjusting the volume flow or flow velocity of a transported medium. The control valve forms part of a prefabricated unit that further comprises an input pressure transmitter (28), an output pressure transmitter (30) and an electronic control device (24).
