COMFORT Safety Group No. 25 DN 15 A25 8 bar 24.2 LF

The Safety Group 25 DN 15 A25 8 bar Lead Free provides 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 compactly contains all components prescribed by DIN 1988 for DHW equipment. The safety valve protects the downstream DHW, and the backflow preventer prevents the backflow of heated drinking water. In addition, a pressure reducer is connected upstream to regulate the required system pressure. The 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, and the valve cap is made of glass fiber reinforced plastic. 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.
