Derry Traditional - Polished Brass Thermostatic Radiator Valve & Lockshield Angled 10mm

Smarter room comfort from a thermostatic valve set

This traditional Derry Traditional 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 angled body connects to 10mm pipework, while the wax sensor responds automatically to changes in room temperature.

Why choose these radiator valves?

• Give each room its own level of heating control: The thermostatic head responds to room temperature and regulates hot-water flow through that radiator as the selected comfort level is reached.
• Use less unnecessary heat in rooms that are already warm: 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.
• 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.
• Simplify the purchase with both valves supplied: Supplying a matching lockshield alongside the TRV means both visible valve positions can be completed as one coordinated set.
• Plan the radiator connection with the right valve shape: For side-entry radiators with pipes coming up from the floor, the angled body turns the connection neatly into the radiator.
• Choose a heating level that suits the space: Several thermostatic settings give you more flexibility than a simple manual on/off valve.
• Let the valve respond automatically to room temperature: Temperature changes cause the wax sensor to expand or contract, allowing automatic control of the valve mechanism.
• Make the valve set part of the radiator's overall look: A traditional silhouette gives the valve set more visual character than a purely functional modern fitting. Its polished & un-lacquered Polished Brass surface lets the valves become part of the radiator's overall finish rather than an afterthought.
• Get extra peace of mind after fitting: The included 3 years guarantee adds confidence when choosing a valve set for ongoing everyday use.
