EC type-tested and certified
Air/Gas Control GIK40R02-5 Kromschroder
1 Application Air/Gas Control GIK40R02-5 Kromschroder
upstream of gas burners in systems without preheated
combustion air.
For use in gas control lines in all sectors of the iron,
steel, glass and ceramics industries, as well as in commercial
heat generation, such as the packaging, paper
and foodstuffs industries. Air/gas ratio controls GIK with inlet pressure compensation
diaphragm and zero shut-off serve to maintain a
constant gas/air ratio and to control the gas pressure

3 Function
Air/gas ratio control GIK is actuated by the air line pressure.
The valve disc is lifted from the valve seat and the
gas flows into the regulator outlet area via the open
valve seat. The outlet pressure is applied to the space
above the working diaphragm via the impulse line. The
outlet pressure is controlled in a ratio of 1:1 to the air
control pressure. The inlet pressure compensation diaphragm
ensures high control accuracy.
The burner capacity can be adjusted using the air control
valve.
4 Flow rate
Gas type: natural gas,
flow rate Q = 150 m3/h,
inlet pressure pu = 50 mbar,
outlet pressure pd = 20 mbar,
pressure loss Δp = pu – pd = 30 mbar.
The result is intersection P1.
The next largest nominal size is selected:
GIK 50.
