Saunier Duval valve is the directional water device that only appears in combi boilers. It enables hot water to be directed to the heating system radiators or to the domestic hot water system taps or showers. This feature within a Combi boiler means that the boiler does not require a cylinder to store or provide heating and hot water.
This part is suitable for a range of Glow-worm SI, CXI, CI & Saunier Duval Therma classic F and Plus
