In industrial heating applications, achieving the exact stoichiometric mixture often requires more than just standard regulators; it demands the granular control provided by the NV series. These manual valves function by adjusting the position of a tapered needle within the flow path, allowing for incremental changes in gas volume. This is particularly critical during the commissioning phase of a burner, where fine-tuning the gas pressure is essential to achieve a stable flame and minimize emissions.
The technical advantage of the Delta-Elektrogas NV Needle Valves lies in their “balanced” flow design and high-quality sealing materials. The internal needle is precision-machined to ensure that flow adjustments remain consistent over time without drift. Furthermore, the compact design and various port sizes make it easy to integrate into existing burner systems or pilot lines. By utilizing these valves, industrial facilities can significantly improve their process repeatability and reduce the risk of incomplete combustion or fuel wastage.
The Delta-Elektrogas NV Needle Valves are high-precision flow control instruments engineered for the fine adjustment of gas and air supply in industrial combustion systems. Designed to provide a reliable manual throttling solution, these valves allow operators to calibrate the gas flow with extreme accuracy, ensuring optimal burner performance and energy efficiency.
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.
