Kromschroeder VAG240R/NQAE (88000290) régulation du rapport air/gaz

Gas valve Kromschroder VAG240R/NQAE (88000290) Air/gas ratio controller with solenoid valve Kromschroder VAG240R/NQAE — precise stoichiometric combustion for powerful industrial systems. Kromschroder VAG240R/NQAE is an air/gas ratio controller with integrated solenoid valve class A (EN 88 and EN 161). Designed to maintain a constant gas/air ratio of 1:1 in modulating gas burners of medium and high power, ensuring optimal combustion and high efficiency. Main advantages: Precise 1:1 ratio — automatically maintains ideal gas/air proportion over the entire modulation range. Minimal NOx and CO emissions, maximum thermal efficiency. Low outlet pressure — NQ modification for precise operation in low pressure range (similar to 2.5–25 mbar in the series). Fast-acting solenoid valve — quick opening and closing for reliable gas shut-off. High safety — class A according to EN 161, maximum inlet pressure 500 mbar. Size DN 40 (1½") — Rp internal thread. Optimal for medium and high capacity systems. Premium quality — original Kromschroder (Honeywell). Full certification EC, FM, CSA, UL. Works with natural gas, LPG, biogas and air. Technical features: Air and gas pressure range: 0.5–100 mbar Servo technology for precision control Protection class IP65 Position indicator, pressure test points Voltage: 230 V AC (standard for most versions) Operating temperature: -20…+60 °C Application: Modulating industrial gas burners of high power Large boiler houses and heat generating equipment Drying chambers, furnaces, heat treatment lines Systems with variable heat load Modernization of existing
