Aylesbury 'KS' Type


The ‘KS’ Type valve, made in high grade (minimum 316L) stainless steel is identical in operation to the ‘K’ Type valve and is generally used where water conditions require stainless steel. Typically for seawater, demineralised water and process applications.

The weighted key-shaped float which is supplied with Aylesbury ‘KS’ 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.
