In modern industrial heating, achieving the perfect stoichiometric mixture is essential for reducing emissions and maximizing heat output. The RAG series operates as a ratio controller where the outlet gas pressure is governed by a control air pressure signal. As the burner’s air demand changes, the regulator automatically adjusts the gas flow to maintain a fixed 1:1 ratio (or modified via spring adjustment), ensuring a consistent flame profile and preventing fuel-rich or lean conditions.
The Delta-Elektrogas RAG Air/Gas ratio regulators feature a balanced valve mechanism that compensates for upstream pressure variations, providing a stable outlet pressure regardless of supply fluctuations. The internal diaphragms are made from high-strength NBR reinforced with synthetic fibers, ensuring long-term durability against mechanical stress. Furthermore, the design includes a bypass for adjusting the minimum flow (start gas), allowing for smooth ignition sequences. Whether used in high-temperature furnaces or steam boilers, the RAG series provides the technical precision required for sophisticated burner management systems.
The Delta-Elektrogas RAG Air/Gas ratio regulators are high-precision devices engineered to maintain a constant air-gas ratio in combustion systems. By utilizing advanced pneumatic feedback, these regulators ensure that gas pressure follows the combustion air pressure proportionally, delivering optimal fuel efficiency and stable burner performance across various firing rates.
In 1961 Elettromeccanica DELTA s.p.a. was founded in Arcade (TV) with the aim of designing and manufacturing oil burners with mechanical atomization. Today, Elettromeccanica DELTA and its brand Deltapumps and Elektrogas are leading manufacturers of gear oil pumps and safety control valves, exported in more than 60 countries in the world.
