Kartell K-Design Thermostatic Radiator Valve Twin Pack

This Twin Pack delivers precise, room-by-room temperature control with a clean contemporary finish suited to modern bathrooms and living spaces. Available in straight, corner, and angled configurations to suit every installation type — whether your pipework runs horizontally from the wall, vertically from the floor, or at a mid-height angle — each twin pack includes a flow TRV and lockshield return valve for a complete radiator connection. The seven-position thermostatic wheel head provides temperature control between 7°C and 32°C, with a built-in frost protection mode at the * setting. All valves are bi-directional and can be installed on either the flow or return pipework when used with a system automatic bypass valve, meeting Building Regulations requirements for all new installations and boiler upgrades.
