Product Description
Kromschroder GIK-25R02-5 Pressure Regulating Valve for Gas Industrial Burners
Description
The air/gas ratio controls GIK and GI serve to maintain a constant air-gas ratio and to regulate the gas pressure upstream of gas burners on installations without preheated combustion air. GIK and GI for continuous control (Fig. 1), GIK..B with bypass for high/low/off control (Fig. 2). Zero-pressure regulation with conversion kit (Fig. 7). EN 746-2 demands that a burner always be ignited with a stable gas-air mixture. This requirement can be met with the aid of the air/gas ratio
control. EC type-tested and certified to the Gas Appliance Directive (90/396/EEC).
For maintaining a constant air-gas mixture
For continuous and step-by-step burner control
High regulating precision
Wide regulating range
Maintenance-free
EC type-tested and certified
Features
- The GIK can be converted to the GIK..B. The bypass screw must be exchanged for this purpose.
- With spring for compensating for the weight of the metering assembly in the case of continuous control.
- Air/gas ratio control with inlet pressure compensation diaphragm and zero shut off.
Bypass diameter GIK..B:
GIK 15-25:
standard 1.5 mm, possible to 4 mm,

Function
The air/gas ratio control is activated by the pressure of the air line. It regulates the gas outlet pressure pa in the ratio 1:1 to the air control pressure pL. The burner capacity is varied with the aid of the air valve. Furnace pressure fluctuations have the same effect on gas and air throughput, thus meaning that the
gas-air mixture does not change. In the min.-flow range, the gas-air mixture can be set by adjusting the governor
spring. For step-by-step control, the springs are relieved at the factory to ensure that the low-fire rate volume only
flows through the bypass. The setting at high fire is performed via restrictors or valves on the burner.
The GIK, GI for continuous control covers a wide regulating range (Fig. 5).
The GIK..B switches over between min. flow and max. flow (Fig. 6).
