SYR Safety Group 24 SYRobloc DN 20, G1 10bar unfinished brass

The SYR Safety Group 24, DN 20, provides optimal protection against overpressure in closed domestic hot water heaters (DHW), in accordance with DIN 1988, Part 2, DIN 4753, Part 1, and DIN EN 1488. It meets the sound insulation requirements of DIN 4109 (Sound Insulation in Buildings) Class 1 and compactly contains all components prescribed by DIN 1988 and DIN EN 1488 for the equipping of DHW heaters. The safety valve protects the downstream DHW heater, and the backflow preventer prevents the backflow of heated potable water. The Safety Group 24, DN 15, consists of inlet and outlet shut-off valves, a backflow preventer, a pressure gauge connection, a diaphragm safety valve, and a discharge funnel. The easily replaceable diaphragm safety valve, with its wear-resistant stainless steel seat, can be rotated 360 degrees via a screw connection to adapt to different installation conditions. Screw connections with R 1 Technical data: Inlet pressure: 10 bar according to DIN EN 1488 Operating pressure: max. 80% of the safety valve's set pressure Operating temperature: max. 30°C inlet temperature Max. nominal volume DHW: 1000 liters Set pressure: Factory setting: 10 bar Medium: Potable water Component test no.: TÜV-SV-20-545-DN-W-p Installation position: Any Flow rate: DN 20: 4.0 m³/h at ?p 1.0 bar ABP No.: PA-IX 1794/I
