Product Overview
The KROM SCHRODER GIK 25R02-5 is a precision-engineered air/gas ratio control valve designed for industrial combustion systems. Manufactured by Krom Schroder (Honeywell), this valve maintains a constant air-to-gas ratio across the entire modulating range, ensuring optimal combustion efficiency and emissions control. The GIK series operates on a pneumatic proportional control principle, where the gas flow is mechanically linked to the air flow via a diaphragm actuator, providing accurate and repeatable ratio control without external power requirements. The model designation “25” indicates a nominal connection size of DN25 (1 inch), while “R02” specifies the ratio adjustment range and “5” denotes the spring range configuration. This valve is a critical component in industrial burner management systems, enabling precise fuel-air mixing for stable flame conditions.
