Aylesbury ‘KB’ type float valves are operated by a transfer of weight in an actuator tube which causes the valve to open or close. The arrangement of the float and buoy assembly produces a delayed change of balance in the actuator as the water level alters. The total assembly is relatively light with no pressure related stresses. As a result, the valve does not require any supporting structure.
Aylesbury ‘KB’ type float valves have a variable delayed action and feature a chain in place of a rigid float arm, enabling virtually unlimited opening and closing levels. This allows for a considerable drop from the valve to the water level, overcoming issues associated with drop arms.
The versatility of the Aylesbury ‘KB’ type float valves also make them suitable for installation either directly into a tank or into a raised valve chamber, particularly where air gaps are required. Changes in water levels and differentials can be made quickly by the installer or maintenance engineer without tools.
This feature is particularly useful where water demand changes either due to seasonal factors, building occupancy or where the commissioning of a facility is phased, as it reduces the risks associated with excess water being stored for too long.
