Description
The pressure regulator VAD, air/gas ratio control VAG, and variable air/gas ratio control VAV use servo technology to shut off and precisely control the gas supply to gas burners and gas appliances. They are for use in gas control and safety systems in all sectors of the iron, steel, glass, and ceramics industries, also in domestic or commercial heat generation, such as the packaging, paper, and food industries.
Variable air/gas ratio control VAV, Class A, for maintaining a constant gas/air pressure ratio for modulating-controlled burners. Pressure preset by the air control line. The ratio of gas pressure to air pressure remains constant. It can be set from 0.6:1 to 3:1. Pressure fluctuations in the combustion chamber can be compensated via the combustion chamber control pressure.
