COMFORT Safety Group No. 25 DN15 (1/2") 10 bar made of brass

Safety Group 25, DN 15 provides optimal protection against overpressure in closed potable water heaters (PWH) in accordance with DIN 1988 and DIN 4753, Part 1. It meets the sound insulation requirements of DIN 4109 (Sound insulation in buildings) Class 1 and compactly contains all components required by DIN 1988 for PWH equipment. The safety valve protects the downstream PWH, and the backflow preventer prevents the backflow of heated potable water. Additionally, a pressure reducer is upstream, which regulates the required system pressure. Safety Group 25.2 consists of a pressure reducer, shut-off valve, backflow preventer with test device, pressure gauge connection and diaphragm safety valve, as well as a discharge funnel. The easily replaceable diaphragm safety valve with wear-resistant stainless steel seat can be rotated by 360 degrees via a screw connection for adaptation to different installation conditions. Screw connections with R ½.
