They work according to the 3-chamber system, subdivided into an inlet pressure zone, central pressure zone and rear pressure zone. The system separators have a flange connection (DIN EN 1092-1) for horizontal installation, two non-return valves and dripping water connection as well as three test connection pieces. Nominal connection diameters DN 150 to DN 250 Nominal flow: up to 235 m³/h Nominal pressure PN 10 bar Test connections Connection flange in acc. with DIN ISO 2533 DVGW/SVGW-certified (up to DN 100)
