Keraflo’s latest development, the KP Type float valve kit, allows full flexibility in the level of stored water that is available in large tanks supplied by pipework up to 200mm in diameter. This feature is of particular importance in buildings with seasonal occupancy such as universities and colleges, football stadiums, etc. where the building may be unoccupied during the summer months. Other advantages offered by this type of float valve kit are: delayed action for full flow during tank filling, no water hammer, valve bounce or dribble, tank capacity is maximised and the valves are suitable for Types AA, AB, AF and AG air gaps. The valve kit comprises a Keraflo “Aylesbury” KB Type float valve, which may be located in the tank itself or in a valve chamber, together with a large in-line KP Type control valve mounted in the supply pipework. The KP Type in-line valve, which is available in 50mm, 80mm , 100mm, 150mm and 200mm, may be floor-mounted or, alternatively, located either outside or inside the tank itself, above the water level.
