Derry Traditional - Black Thermostatic Radiator Valve & Installation Kit Corner 15mm (130mm version)

Control radiator warmth with greater precision

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 15mm pipework, while the wax sensor responds automatically to changes in room temperature.

Why choose these radiator valves?

• Give each room its own level of heating control: Thermostatic control lets this radiator react to the temperature of its own room rather than relying only on the main heating controls.
• Make more efficient use of your central heating: Restricting flow when less heat is needed can help prevent an already-comfortable room from continuing to receive unnecessary radiator heat.
• Keep a layer of frost protection in reserve: 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: Both the thermostatic side and matching lockshield are included, simplifying the parts you need to source for the radiator.
• Use a fitting designed around your pipe direction: For pipework coming straight from the wall to a side-entry radiator, this corner layout keeps the connection compact.
• Tailor radiator output to the room's needs: The multi-temperature head lets you select different heating levels to suit how much warmth the room needs.
• 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.
• Choose a finish that complements the installation: A traditional silhouette gives the valve set more visual character than a purely functional modern fitting. Its matt Black surface lets the valves become part of the radiator's overall finish rather than an afterthought.
• Get extra peace of mind after fitting: A 3 years guarantee gives you longer-term reassurance beyond the initial installation.
