Stirling Bold - Black Thermostatic Radiator Valve & Lockshield Straight 8mm

Room-by-room comfort with thermostatic radiator control

Designed to combine individual radiator control with a coordinated finish, this Black Stirling Bold thermostatic valve set includes both the TRV and matching lockshield. Its straight layout suits the relevant pipe route, and the liquid sensing mechanism adjusts the valve as surrounding temperature changes.

Why choose these radiator valves?

• Give each room its own level of heating control: Thermostatic control lets this radiator react to the temperature of its own room rather than relying only on the main heating controls.
• Reduce unnecessary radiator heating: By reducing hot-water flow when the room is warm enough, the valve can help limit unnecessary heating in that space.
• Keep a layer of frost protection in reserve: The frost setting provides a safeguard for very cold conditions by allowing the valve to open slightly when temperatures fall sufficiently low.
• Simplify the purchase with both valves supplied: Both the thermostatic side and matching lockshield are included, simplifying the parts you need to source for the radiator.
• Match the fitting to the direction of your pipework: Straight valves suit side-entry radiator layouts where the pipework runs along the wall to meet the radiator.
• Move beyond simple on-or-off radiator control: Multi-temperature adjustment lets the radiator be set to a more appropriate comfort level for the room.
• Let the valve respond automatically to room temperature: The liquid sensor responds to changes in surrounding temperature to operate the thermostatic mechanism automatically.
• Coordinate the valves with the radiator: Its modern profile gives the radiator connection a neater, more streamlined finishing detail. The matt Black finish helps coordinate the valves with the radiator and nearby fittings.
• Buy with longer-term reassurance: A 3 years guarantee gives you longer-term reassurance beyond the initial installation.
