Stirling Bold - Black Thermostatic Radiator Valve & Lockshield Straight 15mm

Thermostatic control with a coordinated valve set

Bring more control to one radiator with this Stirling Bold thermostatic valve set in matt Black. Supplied with a matching lockshield, the straight valve uses a liquid sensor and multi-temperature control to regulate hot-water flow as the room warms and cools.

Why choose these radiator valves?

• Take more control of individual room comfort: Thermostatic control lets this radiator react to the temperature of its own room rather than relying only on the main heating controls.
• Avoid heating a room more than you need: 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.
• Get the complete valve pair in one purchase: The set includes the TRV and matching lockshield together, giving you both radiator valves in one coordinated purchase.
• Use a fitting designed around your pipe direction: Where pipework travels horizontally along the wall into a side radiator connection, the straight body keeps the route direct.
• Adjust the radiator to suit how you use the room: Multi-temperature adjustment lets the radiator be set to a more appropriate comfort level for the room.
• Benefit from automatic response to changing room temperature: The liquid sensor responds to changes in surrounding temperature to operate the thermostatic mechanism automatically.
• Coordinate the valves with the radiator: The contemporary body shape is designed to complement modern radiators without adding unnecessary visual bulk. Its matt Black surface lets the valves become part of the radiator's overall finish rather than an afterthought.
• Choose with added confidence beyond installation: With a 3 years guarantee, the set comes with added reassurance for the years after installation.
