SYR Diaphragm Safety Valve 2115 6bar, 1/2 rough, component-tested

The diaphragm safety valve 2115 is used to protect pressurized liquid systems against overpressure in closed domestic hot water heaters (DHW) in accordance with DIN 1988, Part 200 and 4753, Part 1 and TRD 721. The connection size must be determined according to the heating capacity of the heat generator to be protected, as shown in the table. In addition, the diaphragm safety valve 2115 can be used to protect systems in accordance with AD 2000-Merkblatt A2 with media according to the specified specification. The discharge capacity can be replaced by the values listed in the table. The set pressure of the safety valve, indicated on the black sealing disc pressed into the lifting handle of the valve, must be selected such that the inlet pressure is at least 20% below the maximum permissible operating pressure of the system to be protected. The diaphragm safety valve 2115 is designed with a pre-connected seat seal separated from the diaphragm. It can be opened via the rotary handle. Technical data: Operating temperature: max. 110 °C Connection size: DN 15 Set pressure: 6 bar Installation position: preferably main axis vertical, inlet connection at bottom Component test no.: TÜV-SV-20-545-DN-W-N-p Medium: Water, neutral, non-adhesive liquids
