Kentwell Thermostatic Radiator Valve Set

The Kentwell is a traditional angled thermostatic radiator valve (TRV) and lockshield set, with the proportions and detailing of early twentieth-century valves. It suits our Victorian, Nouveau, Powis and other cast iron radiators, and lets each room be controlled individually without looking out of place in a period interior.

Each set is a pair: a thermostatic valve with a traditional head for one end of the radiator, and a matching lockshield for balancing at the other. Valves are angled, for pipes rising from the floor, and fit 15mm copper pipe with ½” BSP radiator connections. The thermostatic head sets the room temperature up to about 30°C; turned fully clockwise, it closes but still opens below about 6°C to give frost protection. The thermostatic valve is not bi-directional: it must be fitted on the flow pipe, or it may be noisy in use.

Finishes and prices

Choose a finish that relates to the room’s door and window furniture: antique brass and antique copper sit well with aged ironmongery, polished brass and chrome with brighter fittings. You need one set per radiator. Valves carry a 5-year guarantee. Because valves are made to order, we can only accept returns if an item is faulty or damaged in transit.

The system should be flushed and dosed with inhibitor to BS 7593. For heat pump systems, thermostatic valves should be set up as the heating designer specifies. See our cast iron radiators, or call 0333 987 4452.
