Description
These are a pair of manual angled radiator valves in an anthracite finish, supplied as Tower (TFC Group) Product Code MRVM-A. They are simple shut‑off/flow control valves intended for use on domestic and light commercial central heating systems where the pipework meets the radiator inlet at a right angle or where the pipe rises from the floor to the valve. As manual valves they give you straightforward on/off and coarse flow adjustment rather than automatic temperature control.

What these valves do and when to choose them
Angled radiator valves like these provide the connection between the heating pipework and the radiator. The 90° (angled) body suits installations where the pipe comes up from the floor or exits the wall below the radiator outlet. Because the pair is sold together you can fit one as the inlet control (the flow valve) and the other as the return/lockshield for system balancing.
Design, finish and practical appearance
The anthracite finish is a contemporary dark grey that’s intended to match modern radiators and fixtures better than bright chrome. It’s a surface coating intended to resist everyday wear; however, like any coloured finish, it will show scratches or chips more obviously than plain chrome, so take care during installation and consider touching-up or protective sleeves if the valves will be moved frequently during building work.
Installation, compatibility and practical notes
The valves use a 15mm pipe connection and a 1/2″ BSP radiator tail. That combination is standard on the majority of modern radiators and towel rails, so they will fit straightforwardly in most installs. If your existing radiator uses a different spud size or non‑standard tailpiece you may need an adaptor or a different valve style. The valves are rated to a maximum flow temperature of 120°C and to 10 bar working pressure, which covers normal domestic central‑heating conditions and the occasional higher‑temperature service in commercial settings.
Because these are manual valves (not thermostatic) they don’t regulate room temperature automatically. If you need automatic temperature control you would use a thermostatic radiator valve (TRV) on the inlet and a lockshield on the return. That said, a manual pair like this is a correct choice for systems where manual isolation is required or where TRVs are used elsewhere on the circuit.
Size and handling
The manufacturer lists the assembled pack dimensions and mass: approximately 75 × 35 × 120 mm and 0.438 kg. These are compact components but make sure you have physical access to tighten compression fittings and to set the lockshield once fitted. If pipes are painted or have excess flux/debris, clean them before assembly to avoid scratching the finished surface.
Advantages and limitations
- Advantages: economical, colour‑matched anthracite finish for modern schemes; standard 15mm / 1/2″ connections mean broad compatibility; sold as a matching pair for neat installations.
- Limitations: manual operation only (no thermostatic control); coloured finish requires care during installation to avoid damage; check radiator tail/spud sizes before ordering to avoid adaptors.
Overall, the Tower MRVM-A anthracite angled radiator valves are a practical, cost‑effective solution for anyone fitting or replacing radiator valves where a colour‑matched, contemporary finish and standard 15mm/1/2″ connections are required. They suit new installs and retrofit work provided you accept manual control and ensure the radiator tails match the 1/2″ BSP connection.
