Derry Traditional - Black Nickel Thermostatic Radiator Valve & Lockshield Corner 10mm

Thermostatic control with a coordinated 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 corner body connects to 10mm pipework, while the wax sensor responds automatically to changes in room temperature.

Why choose these radiator valves?

• Manage radiator warmth around how the room is used: Thermostatic control lets this radiator react to the temperature of its own room rather than relying only on the main heating controls.
• Avoid heating a room more than you need: 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.
• Match the fitting to the direction of your pipework: Where pipes emerge from the wall into a side radiator connection, the corner format helps keep the valve head tucked closer to the radiator.
• Move beyond simple on-or-off radiator control: Multi-temperature adjustment lets the radiator be set to a more appropriate comfort level for the room.
• Get automatic temperature-responsive control: A wax sensing element reacts to room-temperature changes and adjusts the valve mechanism without constant manual input.
• Choose a finish that complements the installation: The classic valve profile adds a decorative finishing touch that works naturally with traditional radiator styles. The polished & lacquered Black Nickel finish helps coordinate the valves with the radiator and nearby fittings.
• Get extra peace of mind after fitting: With a 3 years guarantee, the set comes with added reassurance for the years after installation.
