COMFORT Safety Group No. 25 DN15 (1/2) 8 bar made of brass

The safety group 25, DN 15, serves as optimal protection against overpressure in closed domestic hot water heaters (DHW), 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 compact form all components prescribed by DIN 1988 for equipping DHW heaters. The safety valve protects the downstream DHW heater, and the backflow preventer prevents the backflow of heated potable water. Additionally, a pressure reducer is installed upstream to regulate the required system pressure. The safety group 25.2 consists of a pressure reducer, shut-off valve, backflow preventer with test device, pressure gauge connection, diaphragm safety valve, and discharge funnel. The easily replaceable diaphragm safety valve with a wear-resistant stainless steel seat can be rotated 360 degrees via a screw connection to adapt to different installation conditions. Screw connections with R ½.
