Common areas of use and applications

The products are mainly used in water-borne heating systems where you want to retain or recreate the old style of the elements. It is common to use straight valves (FVR) or angled valves (FVV) depending on how the pipework to the radiator looks. Together with matching bends with nuts, return valves and nipples in polished brass, you create a uniform and stylish installation that hides modern pipe transitions in an elegant way.

Important things to consider before your purchase

Before ordering components for your castle valves, it is important to check the dimensions of your existing pipes and elements. The most common thread sizes and sizes are G10, G15 and G20. Make sure to choose the right model between straight and angled radiator valves so that they fit your specific pipework. It is also recommended to supplement with the correct combination couplings and nipples from the same manufacturer to ensure that threads and seals fit together perfectly, which minimizes the risk of future installation problems.
