The Aylesbury™ range launched in 1987, a design that pioneered the use of ceramic discs in valves for cold water storage tanks.

Aylesbury valves are designed to provide an accurate and efficient method of controlling the level of stored cold water in tanks with and without raised float valve chambers and are constructed to operate over long periods without the need for maintenance.

Aylesbury ‘K’ Type

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

Available in sizes up to 3″

Variations avaialble:

‘KAX’ type valve. 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.

‘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.

Aylesbury ‘KB’ Type

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.

The versatility of the Aylesbury ‘KB’ Type makes it 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.

Availavble in sizes up to 3″.
