This pack is the alternative for a dark radiator: a \u003cstrong\u003ethermostatic radiator valve\u003c\/strong\u003e and a matching lockshield, both finished in anthracite grey on brass bodies, with a slim round Kartell design head instead of the usual bulky cap. On an anthracite column radiator, a grey designer towel rail or a black panel, the valves read as part of the radiator rather than an afterthought.\u003c\/p\u003e\n\u003cp\u003eThese are \u003cstrong\u003estraight radiator valves\u003c\/strong\u003e: the pipe enters the valve in a straight line and the outlet sits directly above it. That suits pipework rising through the floor into a radiator with connections underneath. If your radiator connects at the side, check the pipe direction first — the guide below explains which pattern you need.\u003c\/p\u003e\n\u003cp\u003eThe thermostatic head reads the room, not the boiler. Set it once and it closes the valve as the room reaches temperature, so a bedroom or a utility stops drawing hot water when it is warm enough. The valve is bi-directional, so it can sit on either pipe, and it connects to standard \u003cstrong\u003e15mm\u003c\/strong\u003e copper with a compression fitting and to the radiator with a ½″ BSPT male coupling.\u003c\/p\u003e\n\u003ch2\u003eWhat the Numbers on the Head Mean\u003c\/h2\u003e\n\u003cp\u003eEach setting corresponds to a room temperature, from frost protection at \u003cstrong\u003e*\u003c\/strong\u003e up to 32°C.
