Valve set for two-pipe heating systems
Duolux 50 has been specially developed for rational and easy-installation radiator attachment. With this connecting system each radiator is directly attached with its own supply and return flow pipe to a central single-storey heating manifold. Centre-to-centre distance of connections 50 mm.
Duolux 50 is a complete valve set for two-pipe heating systems for attaching radiators to single-storey heating manifolds.
Duolux 50 comprises a two-pipe manifold of angle or straight type, riser and thermostatic valve body with black protective cap.
The angle type two-pipe manifold can be fitted both to the right and left of the radiator.
Pipe-side G 3/4 adaptor with cone – fits compression fittings for plastic, copper, precision steel and multi-layer pipe.
The centre-to-centre distance of the pipe connections is 50 mm.
For IMI Heimeier valves, only use the corresponding, designated IMI Heimeier compression fittings (designation e.g. 15 THE).
Thanks to the regulating disk directly on the radiator, the two-pipe manifold can be used for hydraulic balancing. At the same time, this pre-setting assumes the return flow shut-off function. As a result, the radiator can be detached without draining the system.
