Traditional Look, Modern Control

Cast iron radiators deserve fittings that look the part without compromising performance. Thermostatic radiator valves (TRVs) regulate flow automatically. This helps radiators maintain a steady room temperature, while manual valves give simple on/off control when you prefer to set output yourself. 

Whichever route you choose, cast iron radiator valves protect the aesthetic of your radiator and keep your system easy to live with. You’ll also find heritage styling cues, such as wooden wheel heads and knurled details, which are specifically designed to complement period columns and ornate feet.

Choose Your Finish And Fit

From compact cloakrooms to large bay-fronted lounges, there’s a practical fit and a matching finish for every space. Our range includes radiator valves for cast iron radiators in popular sizes and orientations, so you can achieve a tidy, aligned pipe run and a consistent look across the room.

• Types: thermostatic TRVs or manual valves

• Orientations: angled, straight and corner to suit pipework and inlet position

• Connections: common 15mm, with selected options in 10mm and 8mm

• Finishes: polished or brushed brass, nickel, chrome, pewter, copper, black nickel and more

Installation Tips, Care And Next Steps

Check your radiator’s inlet position and the direction of flow arrows on the valve body before fitting, and choose angled, straight or corner to suit your pipework. After installation, start at a mid TRV setting to let the room settle, then fine-tune over a couple of days. Wipe chrome, brass and coloured surfaces with a soft cloth and avoid abrasive cleaners to keep each finish looking its best.
