Aylesbury ''K' Type

Delayed Action Float Valve

Non adjustable opening / closing operating differential approximately 75mm

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. This positive action avoids dribble, reduces noise and allows full flow until the selected closed level is reached. Inherent in the design is a non-adjustable operating differential in water level between opening and closing of approximately 75mm. Also available in stainless steel for use in demanding environments such as desalination plants and sea water.
