Derry Bold - Silver Nickel Thermostatic Radiator Valve & Lockshield Corner 15mm

A complete TRV set for more flexible room heating

The Derry Bold Silver Nickel thermostatic radiator valve and matching lockshield give you room-by-room control over an individual radiator while keeping the installation visually coordinated. Its corner 15mm fitting and liquid 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 valve automatically alters hot-water flow through the individual radiator in response to the room temperature and selected setting.
• Use less unnecessary heat in rooms that are already warm: Restricting flow when less heat is needed can help prevent an already-comfortable room from continuing to receive unnecessary radiator heat.
• Add protection during very cold weather: Its frost-protection function can allow some flow at very low temperatures, helping reduce the risk of water freezing in the radiator and nearby pipework.
• Get the thermostatic valve and matching lockshield together: A matching lockshield is supplied with the thermostatic valve, so the corresponding valve does not need to be bought separately.
• Make the connection work with your installation layout: Where pipes emerge from the wall into a side radiator connection, the corner format helps keep the valve head tucked closer to the radiator.
• 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.
• Benefit from automatic response to changing room temperature: A liquid-filled sensor reacts as the room warms and cools, helping the valve adjust without constant manual intervention.
• Give the radiator a more considered finishing detail: The modern valve shape keeps the installation looking clean and contemporary. The brushed & lacquered Silver Nickel finish helps coordinate the valves with the radiator and nearby fittings.
• Get extra peace of mind after fitting: The 3 years guarantee provides added reassurance for a product intended to remain part of the heating installation for years to come.
