Product Overview
The DUNGS FRS 5065 is a precision-engineered gas pressure regulator designed for reliable pressure control in industrial gas combustion systems. As part of the DUNGS FRS series, this regulator operates on a spring-loaded diaphragm principle, automatically maintaining a constant outlet pressure regardless of fluctuations in inlet pressure or changes in gas flow demand. The FRS 5065 is a direct-acting regulator suitable for natural gas, propane, butane, and other non-aggressive gaseous media, making it an essential component in gas train assemblies for burners, boilers, and industrial heating processes. Its robust die-cast aluminum housing and precision-machined internal components ensure accurate regulation, fast response, and long service life in demanding industrial environments.
