Derry Bold - Black Nickel Thermostatic Radiator Valve & Installation Kit Angled 15mm (130mm version)

Thermostatic control with a coordinated valve set

The Derry Bold Black Nickel thermostatic radiator valve and matching lockshield give you room-by-room control over an individual radiator while keeping the installation visually coordinated. Its angled 15mm fitting and liquid 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: The valve automatically alters hot-water flow through the individual radiator in response to the room temperature and selected setting.
• Reduce unnecessary radiator heating: Once the room needs less heat, the TRV can reduce flow through that radiator, helping make more efficient use of the hot water being circulated.
• Help protect the radiator when temperatures fall: When surrounding temperatures become very low, frost-protection behaviour can permit limited flow to help protect the radiator and connected 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.
• Plan the radiator connection with the right valve shape: Angled valves suit common layouts where pipework rises from the floor to meet a side-entry radiator connection.
• Set the radiator to a more suitable comfort level: Multi-temperature adjustment lets the radiator be set to a more appropriate comfort level for the room.
• Let the thermostatic mechanism respond without constant adjustment: The liquid sensing element changes with room temperature and drives the valve's automatic thermostatic response.
• Make the valve set part of the radiator's overall look: A cleaner modern form helps the valve set feel coordinated with contemporary radiator designs. In polished & lacquered Black Nickel, the set can be matched deliberately with the radiator finish or used as a contrasting detail.
• Add longer-term confidence to the purchase: The included 3 years guarantee adds confidence when choosing a valve set for ongoing everyday use.
