The bypass valve serves to maintain the pump pressure in heating systems at a constant level. This is necessary when the radiator / underfloor heating thermostat valves are closed or almost closed.
The bypass module is simply mounted on the radiator / underfloor heating circuit manifold. The flat-sealing screw connection ensures rapid and reliable long-term connection of the module to the manifolds.
