Technical Specifications
| Specification | Value |
|---|---|
| Connection size | 3/4" |
| Connection type | External thread |
| Operating pressure (max.) | 3 bar |
| Medium temperature (max.) | 110 °C |
| Medium | Water-glycol mixture (in accordance with VDI 2035) |
| Application | Essential in heating systems with many thermostatic radiator valves (TRVs): while the TRVs are open, the automatic bypass valve stays closed; as the TRVs begin to close, it opens and maintains the required water flow through the boiler. It reduces noise caused by excessive water velocity and, by raising the boiler return temperature, helps reduce corrosion caused by flue gas condensation. |
| Warranty | 5 years |
