The Kayla cable operated dual flush valve from Derwent Macdee is one of the number one sellers in the replacement market. The valve is suitable for retro-fit, new installations and high traffic areas and can be used with concealed, close coupled and low level cisterns. The top section of the valve is compatible with the now discontinued AFV40100 and AFV40200 models and simply fits into the existing cradles without removing the cistern. The top of the valve has the codes AFV50100 and AFV50200 and comes complete with an adjustable overflow tube which adjusts from 190mm to 330mm. The new modern colour design replaces the white version. This in no way alters the design and operation of the valve
