Honeywell VT200-15A Thermostatic Radiator Valve
The Classic VT200-15A TRV is top of its class for design, performance, quality and reliability. Its classical looks and unobtrusive design make it suitable for any heating installation. The valve can be mounted vertically or horizontally at either end of a radiator. To work correctly, the Valencia Classic TRV should be installed to a two pipe heating system and also have a free flow of air around the head to sense temperature.
