COMFORT Safety Group No. 25 DN 15 A25 10 bar 24.2 LF

The safety group 25 DN 15 A25 10 bar Lead Free provides optimal protection against overpressure in closed domestic hot water heaters (TWE), in accordance with DIN 1988 and DIN 4753, Part 1. It meets the sound insulation requirements of DIN 4109 (Sound insulation in building construction) class 1 and contains in a compact form all components required by DIN 1988 for the equipment of TWEs. The safety valve protects the downstream TWE, and the backflow preventer prevents the backflow of heated drinking water. In addition, a pressure reducer is installed upstream, which regulates the required system pressure.\nThe safety group 25 DN 15 A25 consists of a pressure reducer, double shut-off, backflow preventer with test device, pressure gauge connection and diaphragm safety valve, as well as an extendable discharge funnel. The housing is made of lead-free brass, the valve cap of glass fiber reinforced plastic.\nThe easily replaceable diaphragm safety valve with wear-resistant stainless steel seat can be rotated 360 degrees via a screw connection for adaptation to different installation conditions. Screw connections with R ½.\n\nTechnical data:\n Inlet pressure: 10 bar according to DIN EN 1488\n Operating pressure: max. 80% of the set pressure of the safety valve\n Operating temperature: max. 30 °C inlet temperature\n Pressure reducer setting range: 1.5 - 10 bar (factory setting 4 bar)\n Max. nominal volume TWE: 200 liters\n Max. heating capacity TWE: 75 kW\n Set pressure: Factory setting: 10 bar\n Medium: Drinking water\n Installation position: any\n Flow rate: 1.3 m³/h at ∆p 1.1 bar
