Signature Metal Head - Black Nickel Thermostatic Radiator Valve & Lockshield Angled 8mm
Product code: 21684
Smarter room comfort from a thermostatic valve set
Designed to combine individual radiator control with a coordinated finish, this Black Nickel Signature Metal Head thermostatic valve set includes both the TRV and matching lockshield. Its angled layout suits the relevant pipe route, and the wax sensing mechanism adjusts the valve as surrounding temperature changes.
Why choose these radiator valves?
- Set each room's warmth more independently: 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.
- Reduce the risk of freezing in colder conditions: Its frost-protection function can allow some flow at very low temperatures, helping reduce the risk of water freezing in the radiator and nearby pipework.
- Avoid sourcing a matching lockshield separately: A matching lockshield is supplied with the thermostatic valve, so the corresponding valve does not need to be bought separately.
- Use a fitting designed around your pipe direction: Angled valves suit common layouts where pipework rises from the floor to meet a side-entry radiator connection.
- Move beyond simple on-or-off radiator control: Multi-temperature control provides a choice of thermostatic settings rather than limiting the radiator to fully open or fully closed.
- Use a sensor that reacts as the room warms and cools: The wax sensor changes with the surrounding temperature, driving the valve's automatic thermostatic response.
- Make the valve set part of the radiator's overall look: The traditional valve shape gives the installation a more period-inspired finishing detail. Its polished & lacquered Black Nickel surface lets the valves become part of the radiator's overall finish rather than an afterthought.
- Buy with longer-term reassurance: The included 5 years guarantee adds confidence when choosing a valve set for ongoing everyday use.

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.
