Product Overview
The DUNGS FRS 515 is a precision-engineered gas pressure regulator designed for industrial gas train applications, providing accurate downstream pressure control for natural gas, propane, and other non-aggressive gaseous media. Manufactured by DUNGS (Karl Dungs GmbH & Co. KG), a global leader in gas safety and control technology, the FRS 515 operates on a spring-loaded diaphragm principle with a balanced valve seat design. It maintains a constant outlet pressure regardless of variations in inlet pressure or flow demand, making it an essential component in industrial combustion systems, gas-fired process equipment, and safety shut-off chains. The regulator is suitable for direct installation in gas trains upstream of burners and appliances, ensuring stable combustion and compliance with international gas appliance directives.
