Stirling Bold - Polished Brass Thermostatic Radiator Valve & Installation Kit Straight 15mm (130mm version)

Control radiator warmth with greater precision

The Stirling Bold Polished Brass thermostatic radiator valve and matching lockshield give you room-by-room control over an individual radiator while keeping the installation visually coordinated. Its straight 15mm fitting and liquid sensor combine practical connection design with automatic thermostatic response as the room temperature changes.

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.
• 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.
• Help protect the radiator when temperatures fall: 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: Supplying a matching lockshield alongside the TRV means both visible valve positions can be completed as one coordinated set.
• Match the fitting to the direction of your pipework: Where pipework travels horizontally along the wall into a side radiator connection, the straight body keeps the route direct.
• Set the radiator to a more suitable comfort level: The multi-temperature head lets you select different heating levels to suit how much warmth the room needs.
• Let the thermostatic mechanism respond without constant adjustment: A liquid-filled sensor reacts as the room warms and cools, helping the valve adjust without constant manual intervention.
• Complete the radiator with a coordinated visible fitting: A cleaner modern form helps the valve set feel coordinated with contemporary radiator designs. The polished & lacquered Polished Brass finish helps coordinate the valves with the radiator and nearby fittings.
• Choose a valve set backed beyond installation: The included 3 years guarantee adds confidence when choosing a valve set for ongoing everyday use.
