Derry Bold - Pewter Thermostatic Radiator Valve & Lockshield Corner 15mm

Control radiator warmth with greater precision

Designed to combine individual radiator control with a coordinated finish, this Pewter Derry Bold thermostatic valve set includes both the TRV and matching lockshield. Its corner 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: Instead of leaving the radiator fully open, the TRV adjusts the flow of hot water as the surrounding room temperature changes.
• Use less unnecessary heat in rooms that are already warm: Restricting flow when less heat is needed can help prevent an already-comfortable room from continuing to receive unnecessary radiator heat.
• Reduce the risk of freezing in colder conditions: 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: A matching lockshield is supplied with the thermostatic valve, so the corresponding valve does not need to be bought separately.
• Match the fitting to the direction of your pipework: For pipework coming straight from the wall to a side-entry radiator, this corner layout keeps the connection compact.
• Move beyond simple on-or-off radiator control: The multi-temperature head lets you select different heating levels to suit how much warmth the room needs.
• Use a sensor that reacts as the room warms and cools: The liquid sensing element changes with room temperature and drives the valve's automatic thermostatic response.
• Make the valve set part of the radiator's overall look: Its modern profile gives the radiator connection a neater, more streamlined finishing detail. The Pewter colour with a matt & lacquered finish gives the visible valve set a considered decorative appearance.
• Get extra peace of mind after fitting: With a 3 years guarantee, the set comes with added reassurance for the years after installation.
