Derry Traditional - Anthracite Thermostatic Radiator Valve & Lockshield Corner 8mm
Product code: 50071
Control radiator warmth with greater precision
Designed to combine individual radiator control with a coordinated finish, this Anthracite Derry Traditional thermostatic valve set includes both the TRV and matching lockshield. Its corner layout suits the relevant pipe route, and the wax sensing mechanism adjusts the valve as surrounding temperature changes.
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: 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.
- Finish both sides of the radiator with one set: The set includes the TRV and matching lockshield together, giving you both radiator valves in one coordinated purchase.
- Match the fitting to the direction of your pipework: For pipework coming straight from the wall to a side-entry radiator, this corner layout keeps the connection compact.
- Adjust the radiator to suit how you use the room: 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: Temperature changes cause the wax sensor to expand or contract, allowing automatic control of the valve mechanism.
- Make the valve set part of the radiator's overall look: Its traditional form suits column radiators and interiors where the valves are intended to contribute to the overall look. Its matt Anthracite surface lets the valves become part of the radiator's overall finish rather than an afterthought.
- Choose a valve set backed beyond installation: A 3 years guarantee gives you longer-term reassurance beyond the initial installation.

Watts & BTUs (British Thermal Units) Explained
What is a Watt?
Watts are our main unit of energy/power in the UK, commonly associated with lightbulbs and Home Energy performance certificates (EPCs).
What is a BTU?
BTUs are the unit of measurement used to portray a radiators heat output and a rooms heating requirement. 1 Watt is equal to 3.41 BTUs.
Why are they important?
We buy radiators to heat our homes, right? So, we need a way of knowing if a radiator is powerful enough to heat the room that we are shopping for - Watts and BTUs provide us with a value that makes its easier to compare radiators and ultimately choose the right one for our heating requirement.
Need help figuring out how much heat your room needs?
Our fast and easy-to-use BTU calculator can help you:
- Work out a heating requirement value (in BTUs & Watts) for your room
- Show you in-stock radiator recommendations that can fulfil this heat requirement
Delta (Δ) Ratings Explained
What is a Delta (Δ) Rating?
When discussing heat outputs, the Delta rating is the difference between the temperature of the water inside the heating system and the desired temperature of the room.
What does the value represent?
In simple terms, this value is about heat loss. Heating a room only works, if the radiator output exceeds the heat loss of the room.
We use this calculation to make it easy to choose a radiator that will have a heat output that exceeds the heat loss of the room when connected to your heating system type.
If you don't know the room heat loss, you can use our calculator to find out.
What Delta Rating should I use?
- Δ50 = Gas or oil boiler with a flow temperature of around 75°C and a return temperature of around 65°C.
- Δ30 = Low temperature systems e.g heat pumps.
