Keraflo Float Valve Aylesbury KB – 3/4″ (20mm) Pipe Diameter (WRAS Approved Valve)
Keraflo Float Valves are delayed action type valves, WRAS approved, suitable for flanged and round water tanks with or without raised valve chambers.
20mm pipe diameter float valves have maximum static pressure of 10 bar – maximum flow rate is 3 m/s nominal pipe velocity (contact T&D for Keraflo flow rate and pipe velocity charts).
Installation of float valves should be in accordance with the water supply (water fittings) regulations 2010 and BS 8558:2011.
Aylesbury KB type float valves must be attached to vertical NOT sloping walls and are available in a range of sizes to suit pipe diameters 20-80mm.

Float Valves – Keraflo Aylesbury KB Type
Keraflo Aylesbury ‘KB’ type float valves feature a weighted float and buoy that can be accurately set in virtually an unlimited number of positions on the variable chain. The float actuates 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 water flow until the selected closed level is reached by the valve.
