Stirling Bold - Polished Brass Thermostatic Radiator Valve & Lockshield Corner 10mm

Control radiator warmth with greater precision

This modern Stirling Bold TRV set pairs a thermostatic radiator valve with a matching lockshield, helping you manage the warmth of an individual room without relying only on the main heating controls. The corner body connects to 10mm pipework, while the liquid sensor responds automatically to changes in room temperature.

Why choose these radiator valves?

• Set each room's warmth more independently: The valve automatically alters hot-water flow through the individual radiator in response to the room temperature and selected setting.
• Avoid heating a room more than you need: Restricting flow when less heat is needed can help prevent an already-comfortable room from continuing to receive unnecessary radiator heat.
• Add protection during very cold weather: 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: Both the thermostatic side and matching lockshield are included, simplifying the parts you need to source for the radiator.
• Choose a valve body that suits your pipe route: 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: The multi-temperature head lets you select different heating levels to suit how much warmth the room needs.
• Let the valve respond automatically to room temperature: Room-temperature changes are detected by the liquid sensor, allowing the valve to regulate flow automatically.
• Give the radiator a more considered finishing detail: The contemporary body shape is designed to complement modern radiators without adding unnecessary visual bulk. The polished & lacquered Polished Brass finish helps coordinate the valves with the radiator and nearby fittings.
• Choose with added confidence beyond installation: A 3 years guarantee gives you longer-term reassurance beyond the initial installation.
