Derry Traditional - Black Thermostatic Radiator Valve & Lockshield Angled 10mm

A complete TRV set for more flexible room heating

The Derry Traditional Black thermostatic radiator valve and matching lockshield give you room-by-room control over an individual radiator while keeping the installation visually coordinated. Its angled 10mm fitting and wax sensor combine practical connection design with automatic thermostatic response as the room temperature changes.

Why choose these radiator valves?

• Give each room its own level of heating control: 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: Restricting flow when less heat is needed can help prevent an already-comfortable room from continuing to receive unnecessary radiator heat.
• Give the heating system extra protection from freezing 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: The set includes the TRV and matching lockshield together, giving you both radiator valves in one coordinated purchase.
• Match the fitting to the direction of your pipework: Where pipework approaches a side-entry radiator from the floor, an angled valve provides the change in direction needed at the connection.
• Move beyond simple on-or-off radiator control: 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: Temperature changes cause the wax sensor to expand or contract, allowing automatic control of the valve mechanism.
• Coordinate the valves with the radiator: The traditional valve shape gives the installation a more period-inspired finishing detail. Its matt Black surface lets the valves become part of the radiator's overall finish rather than an afterthought.
• Choose with added confidence beyond installation: The included 3 years guarantee adds confidence when choosing a valve set for ongoing everyday use.
