Description
These are a pair of manual corner radiator valves finished in anthracite, sold under Tower (the TFC Group trade brand) as product code MRVC-A. They are the simple mechanical fittings that connect a radiator to 15mm pipework where the pipe enters the wall or floor beside the radiator, giving a neat, low-profile connection and a darker ‘designer’ finish to match anthracite radiators and trims.
Functionally they are straightforward: each valve provides an on/off/flow control point for the radiator feed and a threaded 1/2″ BSP tail that screws into the radiator’s inlet. The corner body redirects the flow at a right angle so the pipe run can be hidden. Because they are manual valves, temperature is controlled by adjusting the valve spindle by hand or using the valve wheel; these items are not thermostatic valve heads and so do not modulate automatically with room temperature.

Who these suit and where they make the difference
If you’re replacing plain chrome valves to match an anthracite radiator or creating a contemporary look, a matched anthracite pair is a simple, cost-effective upgrade. They are particularly appropriate when pipework is routed from the wall or floor close to the radiator inlet and you want the pipework to sit discreetly. At the listed price point they are an economical option for domestic central-heating systems where you only need manual flow control.
Installation and compatibility notes
The valves use standard sizes: a 1/2″ BSP radiator tail and a 15mm pipe connection, so they are compatible with the common radiator inlet fittings and 15mm copper compression pipework used in most UK homes. That said, small differences in radiator inlet geometry and how the existing pipework has been prepared (for example whether an olive and tailpiece are already fitted) can affect fitment. They are sold as manual corner valves rather than a thermostatic valve pack, so if you need automatic temperature control you should buy a TRV head and compatible TRV body (or a complete TRV pack) instead.
Practical installation points you should expect: isolate and drain the system or work on a drained section, check the radial alignment so the valve spindle and body clear skirting and radiator brackets, and confirm whether any additional fittings (tails, olives or sealing washers) are required for your particular radiator. If in doubt, ask your installer to confirm dimensions and handing – corner valves can be handed and orientation is important for a tidy finish.
Performance, durability and limitations
The MRVC-A pair is specified to withstand up to 120°C and 10 bar working pressure, which is comfortably inside the requirements of domestic hot-water central-heating systems. The anthracite finish gives a contemporary, designer look but like all painted or coated valves it will show wear where it is handled frequently; care should be taken during installation to avoid scratching the surface.
There are a few limitations to be aware of: these are manual flow valves only, not thermostatic control heads; the product listing does not state the valve body material or provide a detailed dimensional drawing for the connection geometry beyond the basic thread and pipe sizes; and no TRV head or lockshield is supplied with a simple two-valve pack. For towel rails, dual-fuel setups or radiators with non-standard inlets, verify compatibility before purchase.
Practical advantages
- Clean, contemporary anthracite finish that pairs well with modern radiators.
- Standard 1/2″ BSP and 15mm sizing keeps them widely compatible and straightforward to fit for a competent installer.
- Economical option when you want a matching aesthetic without the complexity or cost of full TRV packs.
In short, the MRVC-A anthracite corner valves are a practical, low-cost finishing piece for a modern radiator installation where manual control is acceptable. They tidy-up corner feed pipework and keep the visual focus on the radiator rather than bright metal fittings. If you need automatic temperature regulation, or you require detailed material data and dimensional drawings for an unusual installation, look for a TRV pack or request technical documents from the supplier before buying.
