Air/gas ratio control

Pneumatic ratio control is implemented with air/gas ratio controls in accordance with EN 12067-1, whereby combination controls, which also act as shut-off val-ves, are used frequently (Fig. 4). Depen-ding on the design of the control, one can distinguish between air/gas ratio controls and variable air/gas ratio
