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

A complete TRV set for more flexible room heating

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 angled body connects to 10mm pipework, while the wax sensor responds automatically to changes in room temperature.

Why choose these radiator valves?

• Set each room's warmth more independently: 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.
• Keep a layer of frost protection in reserve: 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: Supplying a matching lockshield alongside the TRV means both visible valve positions can be completed as one coordinated set.
• Plan the radiator connection with the right valve shape: The angled format is designed for pipe routes that need a 90-degree turn into a side radiator connection, such as pipework rising from below.
• Tailor radiator output to the room's needs: Several thermostatic settings give you more flexibility than a simple manual on/off valve.
• Use a sensor that reacts as the room warms and cools: A wax sensing element reacts to room-temperature changes and adjusts the valve mechanism without constant manual input.
• Give the radiator a more considered finishing detail: The traditional valve shape gives the installation a more period-inspired finishing detail. The Chrome colour with a polished & un-lacquered finish gives the visible valve set a considered decorative appearance.
• Add longer-term confidence to the purchase: The included 3 years guarantee adds confidence when choosing a valve set for ongoing everyday use.
