Derry Traditional - Anthracite Thermostatic Radiator Valve & Lockshield Angled 15mm

Smarter room comfort from a thermostatic valve set

The Derry Traditional Anthracite thermostatic radiator valve and matching lockshield give you room-by-room control over an individual radiator while keeping the installation visually coordinated. Its angled 15mm fitting and wax sensor combine practical connection design with automatic thermostatic response as the room temperature changes.

Why choose these radiator valves?

• Fine-tune warmth one radiator at a time: Instead of leaving the radiator fully open, the TRV adjusts the flow of hot water as the surrounding room temperature changes.
• 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: When surrounding temperatures become very low, frost-protection behaviour can permit limited flow to help protect the radiator and connected pipework.
• Avoid sourcing a matching lockshield separately: 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.
• Get automatic temperature-responsive control: The wax sensor changes with the surrounding temperature, driving the valve's automatic thermostatic response.
• 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. The matt Anthracite finish helps coordinate the valves with the radiator and nearby fittings.
• Add longer-term confidence to the purchase: The 3 years guarantee provides added reassurance for a product intended to remain part of the heating installation for years to come.
