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.

The VAG air/gas ratio control, Class A, maintains a constant air/gas pressure ratio for modulating-controlled burners or with VAS 1 bypass valve for stage-controlled burners. Pressure is preset by the air control line. The VAG..N can also be used as a zero governor for gas engines.
