The Eucotherm Deluxe Central Valve Set – Angled Chrome hides both flow and return inside a slim H-block, so a single mirror-bright fitting sits directly under 50 mm-centre radiators instead of two separate valves. Solidly built, it uses standard 15 mm compression inlets and a ½-inch BSP tail for a tool-light install on almost any central-connection model. H-block valves like this free wall space. The liquid-sensor thermostatic head lets you dial from frost-safe to setting 5 (about 7–30°C). It also comes with a 2-year guarantee. Shop now.
