Derry Bold - Polished Brass Thermostatic Radiator Valve & Lockshield Corner 8mm

More individual control for your radiator

Bring more control to one radiator with this Derry Bold thermostatic valve set in polished & un-lacquered Polished Brass. Supplied with a matching lockshield, the corner valve uses a liquid sensor and multi-temperature control to regulate hot-water flow as the room warms and cools.

Why choose these radiator valves?

• Fine-tune warmth one radiator at a time: Thermostatic control lets this radiator react to the temperature of its own room rather than relying only on the main heating controls.
• Cut back on wasted heat once the room is comfortable: Automatic flow reduction helps avoid continuing to heat an individual room at full radiator output after it has reached the chosen comfort level.
• Keep a layer of frost protection in reserve: A frost-protection setting helps reduce freezing risk by allowing some hot-water flow when the room temperature drops to a very low level.
• Avoid sourcing a matching lockshield separately: Both the thermostatic side and matching lockshield are included, simplifying the parts you need to source for the radiator.
• Choose a valve body that suits your pipe route: Corner valves are suited to side-entry radiators where the pipework comes directly out of the wall.
• Adjust the radiator to suit how you use the room: Multi-temperature adjustment lets the radiator be set to a more appropriate comfort level for the room.
• Use a sensor that reacts as the room warms and cools: A liquid-filled sensor reacts as the room warms and cools, helping the valve adjust without constant manual intervention.
• Choose a finish that complements the installation: The modern valve shape keeps the installation looking clean and contemporary. The Polished Brass colour with a polished & un-lacquered finish gives the visible valve set a considered decorative appearance.
• Get extra peace of mind after fitting: A 3 years guarantee gives you longer-term reassurance beyond the initial installation.
