SYR Diaphragm Safety Valve 2115 8 bar, 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 output of the heat generator to be protected, as per the table. In addition, the diaphragm safety valve 2115 can be used to protect systems in accordance with AD-Merkblatt A2 with media as specified. The discharge capacity can be replaced from the values listed in the table. The set pressure of the safety valve, marked on the black sealing disc pressed into the lifting handle of the valve, must be selected so 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 using the rotary handle.
