Radiator connection valves series
Duolux is a complete series of valves for radiators in two-pipe or single-pipe heating systems. Centre-to-centre distance of pipe connections 35 mm.
2-pipe system
Technical description
HEIMEIER Duolux is a complete series of valves for two-pipe heating systems. The valves are connected to radiators in single-storey heating circuits.
Duolux is comprised of a two-pipe distributor, an ascending pipe, and thermostatic valve body with black protection cap.
The distributor body is made of corrosion-resistant gunmetal (nickel-plated) and is designed for connections to plastic, copper, precision steel, or multi-layer pipes.
For HEIMEIER valves, use only the HEIMEIER compression fittings which have been designed and indicated for the particular application (e.g. ID no. 15 THE).
The two-pipe distributor equipped with a built-in presetting cone enables hydraulic balancing directly on the radiator.
This presetting concurrently assumes the function of the return shut-off so that the radiator can be removed without draining the system.
Single-pipe system
Technical description
HEIMEIER Duolux is a complete series of valves for radiators in single-pipe heating systems.
Duolux is comprised of a single-pipe distributor, an ascending pipe, and thermostatic valve body with blue protection cap. The distributor body is made of corrosion-resistant gunmetal (nickel-plated) and is designed for connections to plastic, copper, precision steel, or multi-layer pipes.
For HEIMEIER valves, use only the HEIMEIER compression fittings which have been designed and indicated for the particular application (e.g. ID no. 15 THE).
The circuit flow rate is designed to be distributed to 50% radiator and 50% bypass.
In the model with the return shut-off, a radiator may be removed without draining the system. The bypass remains open, independent of the shut-off, so that circuit operation is not interrupted.
