ABSTRACT:
A fluid flow regulation system has an inlet, an outlet, and an adjustable flow regulator connected between the inlet and the outlet. The regulator has a closed position at which a leakage gas flow through the system is established. An extraction device is provided for fluid connection with one or both of the inlet and the outlet and is operable to extract fluid to provide a zero or negative flow from the outlet when the flow regulator is in the closed position.
