In industrial gas management, venting the volume between two safety shut-off valves is a critical safety requirement. The Delta-Elektrogas VMRNA series serves this exact purpose by functioning as an automatic relief valve. Because it is a normally open (NO) valve, it remains open when no power is supplied, allowing gas to flow into the relief line. When the coil is energized, the valve closes instantly, allowing the gas train to pressurize for burner operation.
The Delta-Elektrogas VMRNA Automatic Vent Valve is constructed with a high-quality die-cast aluminum body, making it resistant to the thermal and mechanical stresses found in boiler rooms. Its internal design features NBR-based seals that ensure a bubble-tight shut-off when energized. Furthermore, its modular design allows for the easy addition of visual indicators or closed-position indicator switches. By integrating this valve into your Burner Management System (BMS), you ensure a reliable venting sequence that prevents gas buildup and protects against combustion hazards during shutdown periods.
The Delta-Elektrogas VMRNA Automatic Vent Valve is a specialized safety solution designed for the automatic release of gas into a relief line. Operating as a normally open solenoid valve, it ensures that gas trains are safely vented when the system is de-energized, providing an essential fail-safe mechanism for high-demand industrial combustion environments.
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.
