Derry Traditional - Black Nickel Thermostatic Radiator Valve & Lockshield Corner 8mm

Thermostatic control with a coordinated valve set

This traditional Derry Traditional TRV set pairs a thermostatic radiator valve with a matching lockshield, helping you manage the warmth of an individual room without relying only on the main heating controls. The corner body connects to 8mm pipework, while the wax sensor responds automatically to changes in room temperature.

Why choose these radiator valves?

• Manage radiator warmth around how the room is used: The thermostatic head responds to room temperature and regulates hot-water flow through that radiator as the selected comfort level is reached.
• Make more efficient use of your central heating: Automatic flow reduction helps avoid continuing to heat an individual room at full radiator output after it has reached the chosen comfort level.
• Help protect the radiator when temperatures fall: When surrounding temperatures become very low, frost-protection behaviour can permit limited flow to help protect the radiator and connected pipework.
• Simplify the purchase with both valves supplied: The set includes the TRV and matching lockshield together, giving you both radiator valves in one coordinated purchase.
• 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.
• Set the radiator to a more suitable comfort level: Several thermostatic settings give you more flexibility than a simple manual on/off valve.
• Use a sensor that reacts as the room warms and cools: The wax sensor expands and contracts as surrounding temperature changes, operating the thermostatic mechanism automatically.
• Give the radiator a more considered finishing detail: A traditional silhouette gives the valve set more visual character than a purely functional modern fitting. In polished & lacquered Black Nickel, the set can be matched deliberately with the radiator finish or used as a contrasting detail.
• Get extra peace of mind after fitting: A 3 years guarantee gives you longer-term reassurance beyond the initial installation.
