SAUNIER DUVAL 5404400 DIAPHRAGM ONLY.
Product Information: This part is based around the diverter valve section. The diverter valve is an instrument that only appears in combi boilers. It allows the hot water to be sent to the heating system (radiators, etc.) or to the hot water system (taps, etc.). This feature is what makes a combi boiler so popular due to the fact the boiler can provide hot water and heating without the need for a cylinder.
