Its role is to shut off the water inlet when the maximum level in the tank has been reached. The special design with 2 joints increases the closing pressure as the supply pressure rises and reduces the time for closing/opening the circuit. This avoids long filling times and the associated noise. It is pre-equipped with a protective strainer for mechanical inclusions.
