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

A complete TRV set for more flexible room heating

Designed to combine individual radiator control with a coordinated finish, this Chrome Derry Bold thermostatic valve set includes both the TRV and matching lockshield. Its angled layout suits the relevant pipe route, and the liquid sensing mechanism adjusts the valve as surrounding temperature changes.

Why choose these radiator valves?

• Take more control of individual room comfort: 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: By reducing hot-water flow when the room is warm enough, the valve can help limit unnecessary heating in that space.
• Keep a layer of frost protection in reserve: A frost-protection setting helps reduce freezing risk by allowing some hot-water flow when the room temperature drops to a very low level.
• Get the complete valve pair in one purchase: Supplying a matching lockshield alongside the TRV means both visible valve positions can be completed as one coordinated set.
• Use a fitting designed around your pipe direction: Where pipework approaches a side-entry radiator from the floor, an angled valve provides the change in direction needed at the connection.
• Adjust the radiator to suit how you use the room: Several thermostatic settings give you more flexibility than a simple manual on/off valve.
• Benefit from automatic response to changing room temperature: Room-temperature changes are detected by the liquid sensor, allowing the valve to regulate flow automatically.
• 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. The Chrome colour with a polished & un-lacquered finish gives the visible valve set a considered decorative appearance.
• Choose a valve set backed beyond installation: With a 3 years guarantee, the set comes with added reassurance for the years after installation.
