Abstract: A directional-control valve is connectable to a first main pipe and to a secondary pipe. The valve includes an upstream port and a downstream port connectable to the first main pipe and having identical diameters. A third connection port is connectable to the secondary pipe. A shut-off member is capable of moving at right angles to the main pipe between a closed position and a second open position. In the closed position, the shut-off member includes a first orifice, of a diameter identical to that of the upstream port and downstream port, positioned in line with the upstream port and the downstream port.
