Description

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 food industries.

Flow rate regulators VAH are used to maintain a constant gas/air ratio for modulating-controlled and stage-controlled burners. The gas flow rate is controlled proportionally to the air flow rate. In addition, flow rate regulator VAH is designed as a gas solenoid valve and shuts off the gas or air supply safely.
