Derry Bold - Anthracite Thermostatic Radiator Valve & Lockshield Straight 15mm

Control radiator warmth with greater precision

Bring more control to one radiator with this Derry Bold thermostatic valve set in matt Anthracite. Supplied with a matching lockshield, the straight valve uses a liquid sensor and multi-temperature control to regulate hot-water flow as the room warms and cools.

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.
• Make more efficient use of your central heating: By reducing hot-water flow when the room is warm enough, the valve can help limit unnecessary heating in that space.
• Reduce the risk of freezing in colder conditions: The frost setting provides a safeguard for very cold conditions by allowing the valve to open slightly when temperatures fall sufficiently low.
• 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.
• Make the connection work with your installation layout: The straight format is suited to aligned pipework and radiator connections, avoiding an unnecessary change in direction.
• Tailor radiator output to the room's needs: 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: Room-temperature changes are detected by the liquid sensor, allowing the valve to regulate flow automatically.
• Choose a finish that complements the installation: A cleaner modern form helps the valve set feel coordinated with contemporary radiator designs. The matt Anthracite finish helps coordinate the valves with the radiator and nearby fittings.
• Buy with longer-term reassurance: The included 3 years guarantee adds confidence when choosing a valve set for ongoing everyday use.
