Aylesbury KAX Type mechanical float valves are specified for commercial water systems and provide an accurate and efficient method of controlling the level of stored cold water in tanks with raised float valve chambers.
Precision-engineered and built to last, all Keraflo Aylesbury™ patented delayed action float valves are manufactured under Quality Management Systems certified to ISO.9001:2015 and designed to operate for long periods of time without maintenance.
The valves are easy to install with an ‘up and over’ discharge arrangement which assists in facilitating Type AA, AB, AF, or AG air gap requirements under the Water Regulations.
The Aylesbury range is ideal for pumped systems because the open to closed ‘on/off’ valve operation avoids pump hunting and water hammer. The selected water level is unaffected by pressure fluctuation and the patented ceramic disc sealing mechanism means that there is no seat or washer to wear.
The delayed action of Aylesbury float valves delivers a positive fill to actively churn the water in the tank.
The Aylesbury KAX Type valve’s weighted float can be adjusted to a number of positions on the brass float arm, allowing the tank’s stored water level to be easily modified.
KAX Type mechanical float valves are also available in stainless steel for use in demanding environments such as desalination plants and sea water, in the following single head model sizes: 3/4″ (20mm), 1″ (25mm), 1 1/4″ (32mm), 1 1/2″ High Flow (40mm) and 2″ Standard Flow (50mm). Prices are available on application. For further information, please contact our Customer Service team on 0018 921 9920.
Identical in operation to the K Type, the Aylesbury KAX Type valves have extended drops and are suitable for tanks with raised valve chambers.
The KAX Type valves 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.
To assist with compliance with air gap requirements, the valve discharge is further raised above the centre line of the inlet. The KAX Type is especially suitable for Type AA and AB air gaps.
