This valve includes a first chamber, a second chamber, a seat with a liquid passage, a plug movable between i) an open position and ii) a closed position, and a biasing member for urging the plug toward the closed position. The valve includes an actuating member having a face which sustains an actuating pressure. The actuating member is movable between i) an actuation position for opening the plug and ii) a rest position. The valve operates, selectively: in a feed mode, where the plug is open and the actuating member is at rest, the liquid flowing in one direction throughout the second chamber, or in a latch mode, where the plug is closed and the actuating member is at rest, no liquid flowing in the valve, or in a drain mode, where the plug is open, the liquid flowing in the reverse direction throughout the second chamber.
