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

Smarter room comfort from a thermostatic valve set

Give this radiator its own level of thermostatic control with the Derry Bold Black TRV and lockshield set. The straight 15mm connection is designed for the appropriate pipe route, while the liquid sensor works with the valve to reduce hot-water flow when the room no longer needs as much heat.

Why choose these radiator valves?

• Set each room's warmth more independently: The valve automatically alters hot-water flow through the individual radiator in response to the room temperature and selected setting.
• Reduce unnecessary radiator heating: Restricting flow when less heat is needed can help prevent an already-comfortable room from continuing to receive unnecessary radiator heat.
• Help protect the radiator when temperatures fall: 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.
• Choose a valve body that suits your pipe route: Straight valves suit side-entry radiator layouts where the pipework runs along the wall to meet 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.
• Use a sensor that reacts as the room warms and cools: The liquid sensor responds to changes in surrounding temperature to operate the thermostatic mechanism automatically.
• Complete the radiator with a coordinated visible fitting: The modern valve shape keeps the installation looking clean and contemporary. The matt Black finish helps coordinate the valves with the radiator and nearby fittings.
• Choose a valve set backed beyond installation: The 3 years guarantee provides added reassurance for a product intended to remain part of the heating installation for years to come.
