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

Smarter room comfort from a thermostatic valve set

Designed to combine individual radiator control with a coordinated finish, this Polished Brass 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: 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: Once the room needs less heat, the TRV can reduce flow through that radiator, helping make more efficient use of the hot water being circulated.
• 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.
• Finish both sides of the radiator with one set: The set includes the TRV and matching lockshield together, giving you both radiator valves in one coordinated purchase.
• Plan the radiator connection with the right valve shape: Corner valves are suited to side-entry radiators where the pipework comes directly out of the wall.
• Choose a heating level that suits the space: Multi-temperature control provides a choice of thermostatic settings rather than limiting the radiator to fully open or fully closed.
• 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: A cleaner modern form helps the valve set feel coordinated with contemporary radiator designs. The polished & un-lacquered Polished Brass finish helps coordinate the valves with the radiator and nearby fittings.
• Buy with longer-term reassurance: The 3 years guarantee provides added reassurance for a product intended to remain part of the heating installation for years to come.
