The VAG..N can also be used as a zero governor for gas engines.
Air/gas ratio control VAG
The air/gas ratio control VAG controls the outlet pressure pG depending on the variable air control pressure pL.
The ratio of gas pressure to air pressure remains constant: 1:1.
The VAG is suitable for a control range up to 10:1.
If the burner operates at low-fire rate, the gas/air mixture can be changed by adjusting the zero point spring "N".
