Derry Bold - Black Thermostatic Radiator Valve & Installation Kit Straight 15mm

Thermostatic control and finishing parts in one radiator installation kit

This Black Derry Bold installation kit is more than a thermostatic valve set: it combines the TRV and lockshield with matching pipe covers and the other supplied radiator finishing components. That makes it easier to control the radiator and create a coordinated installation from one set.

Why choose this radiator installation kit?

• Manage warmth at the individual radiator: The TRV automatically adjusts hot-water flow through this radiator as the surrounding room temperature changes.
• Complete both radiator valve positions in one set: The TRV and matching lockshield are included together, giving you both valve positions as one coordinated set.
• Finish the visible radiator pipes at the same time: Matching pipe covers are included to create a cleaner transition between the radiator valves and visible heating pipework.
• Help the radiator heat properly after installation: The bleed valve provides the point needed to release trapped air if it collects in the radiator.
• Finish the remaining radiator port neatly: The kit includes the blanking plug required to finish the unused radiator connection.
• Use the right valve format for the pipe direction: The straight format suits aligned pipework and radiator connections, including side-entry pipework running along the wall or suitable bottom-entry layouts.
• Keep the visible installation coordinated: The contemporary valve design helps the installation feel coordinated rather than purely functional. The Black colour with a matt finish gives the visible parts of the kit a consistent appearance.
• Choose with added confidence beyond installation: The 3 years guarantee provides added reassurance for a product intended to remain part of the heating installation for years to come.
