Optimised hydraulics in the concealed cistern Latest generation fill valves and flush valves

Geberit has optimised the hydraulics in the concealed cistern even further. This is made possible by the perfect interplay between the two coordinated valves inside the cistern, the Type 212 flush valve and the Type 383 fill valve.
Together, they ensure an efficient and quiet water flow. The Type 212 flush valve is a dual-volume unit with a water of volume that can be set between 4 and 7.5 litres in the full flush volume. It has a throttle that can be used to adjust the speed of the flow rate to different WC ceramic appliances in order to prevent any oversplashing of the ceramic appliance. The Type 383 fill valve ensures even and fast filling with minimum noise emission.
