A fluid governing system comprising a fluid inlet with a port coupleable to a downstream pipe segment, a fluid outlet with a port coupleable to an upstream pipe segment, a metering inlet path being in flow communication with the fluid inlet, a metering outlet path being in flow communication with the fluid outlet; the metering inlet path is in flow communication with the metering outlet path through a flow unit articulable between the metering inlet path and the metering outlet path; a pressure responsive sealing diaphragm disposed for selective sealing an inlet port of the metering inlet path; an inlet chamber disposed at a face of the sealing diaphragm being in flow communication with the inlet; a control chamber disposed at an opposite face of the diaphragm; a control fluid duct extending between the inlet and the control chamber, said control fluid duct is configured with pressure regulator; a discharge duct extending between the control chamber and the metering inlet path, said discharge duct is configured with a flow shut-off mechanism. |
