Onyx 15mm x 1/2 Angled White TRV | Single Valve

The Onyx 15mm x 1/2" Angled White TRV is a single thermostatic radiator valve finished in clean white, designed to give automatic, room-by-room temperature control on standard central heating systems. The angled configuration suits typical radiator pipework layouts where the pipe approaches from below or the side. The bi-directional valve body and standard 15mm compression connection make this a straightforward upgrade from an old or worn manual valve, letting you set and maintain your preferred temperature in any room without manual adjustment. TRV Valve Type Angled Orientation 15mm x 1/2" Connection Size White Finish 10 Bar Max Pressure Single Valve Pack Contents Please Note - Single Valve Only This listing is for one thermostatic radiator valve only. A radiator typically needs one TRV and one lockshield valve (or two matching valves) to be fully fitted - check what your radiator already has before ordering, or see our matching lockshield and twin-pack options. Angled Configuration Suits standard radiator pipework layouts where the pipe approaches from below or the side at an angle. Clean White Finish A simple, unobtrusive finish that blends easily into modern bathrooms, kitchens and living spaces. Bi-Directional Valve Body Can be fitted with water flowing in either direction, giving flexibility during installation. Thermostatic Control Automatically adjusts water flow to maintain your chosen room temperature, improving comfort and reducing energy waste. Frost Protection Setting A built-in frost protection setting helps prevent freezing in unheated or infrequently used rooms. Standard 15mm Connection Fits standard 15mm compression pipework with a 1/2" BSP radiator connection.

A radiator normally needs one TRV and one lockshield valve to be properly fitted and balanced. This listing is for the TRV only - check our matching lockshield or twin-pack listings if you need both. What does 'bi-directional' mean for this valve?A bi-directional valve body can be fitted with water flowing in either direction through the valve, which gives more flexibility when planning pipework layouts during installation. What size pipework does this fit?This valve is designed for standard 15mm compression pipework with a 1/2" BSP radiator connection, which fits the majority of UK central heating radiators. Can this be used on a heat pump system?Standard TRVs like this are generally compatible with heat pump systems, but always check your heat pump manufacturer's guidance on valve compatibility and any minimum flow requirements before installation.
