Kromschroeder VAV240R/NWAK (88005515) regulator stosunku powietrza do gazu

Gas valve Kromschroder VAV240R/NWAK (88005515) Variable air/gas ratio controller with solenoid valve Kromschroder VAV 240R/NWAK — flexible combustion control for industrial burners Kromschroder VAV240R/NWAK is a variable air/gas ratio controller with an integrated Class A solenoid valve. Designed for precise proportional regulation of gas supply depending on air flow in modulating gas burners and industrial thermal equipment. Main advantages: Variable air/gas ratio — automatically maintains the set ratio (usually 3:1 or adjustable), ensuring optimal combustion at varying burner output. High efficiency and savings — minimizes gas consumption, reduces NOx and CO emissions, increases system efficiency. Fast-acting solenoid valve — reliable gas shut-off, quick opening and closing. High safety — Class A per EN 88 / EN 161, maximum inlet pressure 500 mbar. Size DN 40 (1½") — Rp internal thread. Ideal for medium and large industrial systems. Reliability Kromschroder (Honeywell) — German quality, full European certification. Long service life in harsh conditions. Technical features: Pressure range: up to 500 mbar Protection class IP65 Position indicator and pressure test points Voltage: 230 V AC Operating temperature: -20…+60 °C Applications: Modulating industrial gas burners Medium and large capacity boiler plants Drying chambers, furnaces, heat treatment lines Systems with variable thermal load Retrofitting existing burner systems Kromschroder VAV240R/NWAK provides flexible and precise combustion control, maximum energy efficiency and safety.
