摘要： The valve includes an intake duct (13) for conveying water into the valve, an externally projecting tubular body (20) of a transparent with an internal cavity (21) and a flow indicator rod (40), slidable inside the valve, with a lower portion in the intake duct (13) and an upper indicator portion in the internal cavity (21) of the transparent body (20). The upper, indicator portion has a first upper area (46) able to indicate no water is flowing and a second, lower area (47) able to indicate that water is flowing through the intake duct (13). The valves includes also a rotatable knob (18) for adjusting the flow of water through the intake duct (13) by means of a shutter, which has the shape of a conical head (41) and which corresponds to the lower portion of the indicator rod (40), and a tubular element (30) coupled axially by threaded means (42) to the transparent body (20) which is secured to the knob (18) in order to adjust upwards or downwards the position of an abutment surface (48) of the rod (40) and thereby cause the closure or degree of opening of the valve.
