Kromschroder valVario VAG Fuel-Air Ratio Control with Built-in Solenoid Valve

Kromschroder VAG is a fuel-air ratio controller that uses servo technology to shut off and control gas supply to burners and appliances. It can be used in gas control and safety systems in the iron, steel, glass, and ceramics industries, as well as in domestic and commercial heat generation in packaging, paper and food processes.

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