Aylesbury Keraflo KB Type Delayed Action Float Valve 40mm

Keraflo have been manufacturing high-quality delayed action float valves in the UK for over 20 years. The Aylesbury range is widely trusted across commercial, industrial, and large-scale domestic water systems worldwide.

Available for next-day delivery when ordered before 12pm.

Its delayed action mechanism keeps the valve closed until the water level drops, then opens fully to deliver a fast and efficient refill. This helps prevent pump hunting, water hammer, and valve chatter, while maintaining a consistent water level even with fluctuating pressure.

Featuring a ceramic disc sealing system, the valve eliminates the need for washers or seats, reducing wear and ensuring long-term performance with minimal maintenance.
