The most common materials used in the manufacturing of valves include:
Brass is the most popular material for valves due to its excellent corrosion resistance, durability, and ability to withstand high temperatures. It's also easy to machine and can be finished in various ways (chrome plating, nickel plating, etc.) to match different designs and room aesthetics.
ABS plastic is often used for components of radiator valves, particularly thermostatic valves (TRVs) for the temperature adjustment controls or decorating caps.
Chrome is not a material in itself but a finish. It provides a shiny, reflective surface that is easy to clean and resistant to corrosion, making it a popular choice for bathrooms and towel rails.
Nickel plating is another example of a finish option for valves, offering a slightly warmer tone than chrome. It's durable and corrosion-resistant, making it suitable for a wide range of interior designs.
