The different types of radiator valve are :
• Thermostatic Radiator Valve
• Manual Radiator Valve
• Dual-Fuel Radiator Valve
• Traditional Radiator Valve
• Modern Radiator Valve
• Straight Radiator Valve
• Angled Radiator Valve
• Corner Radiator Valve

Brass valves are best suited to being used on classically designed radiators, especially if you're purchasing a cast iron radiator. Your radiator's finish also needs to be taken in to account. If, for example, you have an exposed or metallic finish on your radiator, a brass valve will blend in quite nicely.
