Gas valve Kromschroder VAG120R/NQAE (88000288) Air/gas ratio controller with solenoid valve Kromschroder VAG120R/NQAE — precise stoichiometric combustion for low pressure Kromschroder VAG120R/NQAE is an air/gas ratio controller with integrated Class A solenoid valve (EN 88 and EN 161). Designed to maintain a constant gas/air ratio of 1:1 in modulating gas burners operating at low pressure. Key benefits: Precise 1:1 ratio — automatically maintains the ideal gas/air proportion across the entire modulation range, ensuring stable combustion and minimal emissions. Low pressure (NQ) — specially adapted for operation in the low pressure range (2.5–25 mbar), critical for many atmospheric and low-power burners. Fast-acting solenoid valve — quick opening and closing for reliable gas shut-off. Compact size DN 20 (¾") — Rp female thread. Convenient for installation in small and medium power systems. High safety — Class A per EN 161, max inlet pressure 500 mbar. Full certification. Kromschroder (Honeywell) reliability — original German quality proven over decades of operation. Technical features: Air and gas pressure range: low pressure (NQ modification) Protection class IP65 Position indicator, pressure test points Voltage: 230 V AC Operating temperature: -20…+60 °C Applications: Atmospheric and modulating gas burners with low pressure Industrial and commercial boilers Drying chambers, furnaces and heat treatment lines Systems with variable heat load Modernization of existing burner equipment Kromschroder VAG120R/NQAE ensures stable and economical combustion, significant
