Derry Traditional - Polished Brass Thermostatic Radiator Valve & Lockshield Angled 8mm

Control radiator warmth with greater precision

The Derry Traditional Polished Brass thermostatic radiator valve and matching lockshield give you room-by-room control over an individual radiator while keeping the installation visually coordinated. Its angled 8mm fitting and wax sensor combine practical connection design with automatic thermostatic response as the room temperature changes.

Why choose these radiator valves?

• Take more control of individual room comfort: The thermostatic head responds to room temperature and regulates hot-water flow through that radiator as the selected comfort level is reached.
• Make more efficient use of your central heating: 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.
• Give the heating system extra protection from freezing conditions: When surrounding temperatures become very low, frost-protection behaviour can permit limited flow to help protect the radiator and connected pipework.
• 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.
• Use a fitting designed around your pipe direction: Where pipework approaches a side-entry radiator from the floor, an angled valve provides the change in direction needed at the connection.
• 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: The wax sensor changes with the surrounding temperature, driving the valve's automatic thermostatic response.
• Complete the radiator with a coordinated visible fitting: Its traditional form suits column radiators and interiors where the valves are intended to contribute to the overall look. The Polished Brass colour with a polished & un-lacquered finish gives the visible valve set a considered decorative appearance.
• Buy with longer-term reassurance: The included 3 years guarantee adds confidence when choosing a valve set for ongoing everyday use.
