Round Thermostatic Matt Black Radiator Valves Straight 15mm Pair

Upgrade your heating system with these Round Thermostatic Matt Black Straight Radiator Valves, designed to bring energy‑efficient control and modern styling to any room. This matching set includes one thermostatic control valve and one manual lockshield valve — working together to maintain your preferred room temperature, balance your heating system and reduce unnecessary energy use.

The thermostatic head features a clear numbered scale from 1 to 5 (MAX), allowing you to set and automatically hold temperatures between approximately 6°C and 28°C, with a frost‑protection setting for unused rooms. Manufactured from high‑quality solid brass, the valves are built to withstand the pressure and temperature changes of everyday central heating, resisting corrosion, limescale and leaks for long‑term reliability. The premium matt black coating is scratch‑resistant, water‑repellent and easy to wipe clean, making it ideal for bathrooms and perfectly matching modern black radiators, towel rails and fittings.

The straight inline design is ideal where pipework runs directly in line with the radiator inlet, creating a streamlined, unobtrusive finish. Supplied as a complete pair, they feature standard 15mm compression connections and ½ inch BSP (R1/2) threads, making them fully compatible with all UK radiators, heated towel rails, copper pipework and standard central heating systems.
