Regulators with solenoid valves are designed for shut-off, and thanks to the servo technology, for precise control of the gas supply to gas burners and gas appliances. They are used in gas control and safety systems in all sectors of the iron, steel, glass and ceramics industries, as well as in residential or commercial heat generation, such as the packaging, paper and foodstuffs industries.
VAD: universal pressure regulator,
VAG: air/gas ratio control for maintaining a constant gas/air ratio of 1:1,
VAH: flow rate regulator for maintaining a constant gas/air ratio for modulating-controlled and stage controlled burners. The gas flow rate is controlled proportionally to the air flow rate,
VAV: variable air/gas ratio control for maintaining a constant gas/air pressure ratio of 3:1,
