Aylesbury Keraflo K Type Delayed Action Float Valve

Aylesbury Keraflo K Type Delayed Action Float Valve


Aylesbury Keraflo K Type
Delayed Action Float Valve
Suitable for tanks without raised valve chambers
The weighted key-shaped float which is supplied with Aylesbury ‘K’ Type float valves can be accurately set in a number of positions on the brass float arm, actuating the valve at a predetermined difference in water level, driving it fully open or fully closed without water hammer.

Primarily for tanks with raised valve chambers. Identical in operation to the ‘K’ Type, the Aylesbury ‘KAX’ Type Valves have extended drops and are suitable for raised valve chambers. They are primarily designed to fit into chambers or boxes in the covers of tanks calling for Air Gaps or where maximum tank capacity is required.



Aylesbury Keraflo KB Type Fully Variable Delayed Action Float Valve

Aylesbury Keraflo KB Type Fully Variable Delayed Action Float Valve


Aylesbury Keraflo KB Type Fully variable delayed action.
Fully variable opening and closing operating differential of up to 1820mm. Suitable for tanks with or without raised valve chambers. The valve is 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 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.
