Gas-air Ratio Control

gas air ratio regulator SET282 can be used as follows:
1- Zero regulator, keeps the downstream pressure uniform from low to high capacities.
2- Air/gas ratio regulator, keeps the air/gas ratio constant even when changing the air pressure.
Based on the pressure ratio, product selection and installation layout should be as follows:
Gas/Air pressure in a ratio of 1:1
Gas/Air pressure from 1:2 ratio to 1:10 ratio (Requires a proportional valve in the air sensor line)
Gas/Air pressure from 2:1 ratio to 10:1 ratio (Requires a proportional valve in the gas sensor line)
