Automatic air vent valve for solar thermal systems Giacomini R99S

The R99S automatic air vent valve is ideal for use in solar thermal systems. It bleeds off the air that forms in the solar circuit, especially during the system filling phase. This avoids any negative effects that could jeopardise the efficiency and lifespan of the system. It is made of special materials that allow operation at high temperatures with glycol water
