FAG

FAG pressure regulators, including the STAB 300-310 series and compact threaded models, are designed to meet UNI EN 88 Class A Group 2 standards. This European standard specifies requirements for gas pressure regulators used in gas appliances and installations, covering safety, performance, and construction. Compliance ensures that the regulators are suitable for use with natural gas, LPG, and non-corrosive gases, with inlet pressures up to 500 mbar and outlet pressure ranges typically from 5 to 300 mbar. The balanced obturator and double safety diaphragm mechanisms provide stable pressure control and fail-safe operation, making them appropriate for industrial combustion systems.

FAG regulator bodies are manufactured from aluminum die-cast alloys, specifically GD AISi 12 EN AB 46100 or G AISi 9 EN AB 43100. These alloys are chosen for their corrosion resistance, which is critical in humid boiler environments where condensation and aggressive gases can degrade lesser materials. The covers are made from zinc alloy, providing additional protection and dimensional stability. This material selection ensures long-term durability and reliable performance, reducing the need for frequent replacements and maintenance in industrial settings.

FAG offers several filter cartridge series, including 10001/02, 10206, 10207/08, 10210, and 10604/5/6. Each series is designed for specific flow configurations and contamination loads, allowing selection based on the analyzer inlet demands and the particulate or moisture levels in the flue gas. For example, the 10001/02 series is a common choice for standard applications, while the 10604/5/6 series may be used where higher filtration capacity is required. These filters remove particulate and moisture before gas enters sensor cells, protecting analyzers and extending service intervals.

FAG flanged pressure regulators, such as the STAB 300-310 series, are rated for a maximum inlet pressure (PS) of 500 mbar. The outlet pressure range is typically 5 to 300 mbar, providing flexibility for various gas control applications. These regulators are available with DN65, DN80, and DN100 flanged connections, making them suitable for different pipe sizes and flow rates. The self-acting design with balanced obturator ensures stable outlet pressure regardless of inlet fluctuations, which is essential for precise combustion monitoring.

Yes, FAG pressure regulators are designed for use with natural gas, LPG, and non-corrosive gases. This makes them versatile for a range of industrial applications, including burner systems, boiler rooms, and gas train installations. The materials and construction are compatible with these gases, and the regulators meet UNI EN 88 Class A Group 2 standards, which cover safety and performance for such media. However, it is important to verify that the specific gas composition and pressure conditions are within the regulator's rated parameters before installation.

FAG filter cartridges are designed to remove particulate matter and moisture from flue gas before it reaches the analyzer's sensor cells. By trapping contaminants, they prevent fouling and corrosion of sensitive components, which can degrade measurement accuracy and lead to frequent calibration or replacement. Using the appropriate filter cartridge for the specific flow and contamination conditions reduces the buildup of deposits, thereby extending the time between maintenance interventions. This contributes to lower operational costs and more reliable continuous monitoring in plant environments.
