FAQ

RADIK - What valves are used in panel radiators of VK design?

The HEIMEIER valve has always been used, as it is the European top in the region.  Numeric designation is stamped on the face of the valve and can be subtracted after removing the manual or thermostat head. If you need to replace a control fitting (valve) in the radiator, it is imperative that the fitting (valve) is identified first by the stamped numbers and only then ordered. These fittings are in no way interchangeable with each other with the exception of 4333 and 4360, which may be interchanged.
