Its purpose 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 periods and the associated noise. It is pre-equipped with a protective strainer for mechanical inclusions. Available diameters: , , 1, 1, 1. Operation: continuous. Operating pressure: 6 bar. Working pressure: 0.2–6 bar. Operating temperature: 0 to +50°C. Storage temperature: -20 to +80°C. Overpressure: 10 bar. Burst pressure: )20 bar.
