3/4" (20mm) Keraflo Aylesbury K Type Delayed Action Float Valve

3/4" (20mm) Keraflo Aylesbury K Type Delayed Action Float Valve - The Keraflo Aylesbury “K” Type Delayed Action Float Valves are designed to provide an accurate and efficient method of controlling the level of stored water in cold water storage tanks without raised chambers.

When the water level inside the tank falls the “K” type valve does not immediately open, there is a delay until the water level has fallen by 75mm, when this occurs the valve moves from a fully closed to a fully open position allowing water to flow back into the tank at a maximum flow rate, when the water level has returned to it’s full level the valve closes preventing any dribbling. This action provides a range of benefits including improved water turnover, fast refilling times, no water hammer and reduced noise. The weighted float can be adjusted to a varitey of positions allowing the water tank level to be easily modified. All valves are WRAS approved. Keraflo valves are manufactured in England and designed to operate for long periods of time without maintenance. The selected water level is unaffected by pressure fluctuation and the patented ceramic disc sealing mechanism means that there is no seat or washer to wear.
