WRAS APPROVED VALVES

WRAS Approved Float Valves

WRAS Approved Float Valves – Keraflo Aylesbury valves are WRAS approved to provide an accurate method of controlling the level of stored cold water in tanks with and without raised float valve chambers.

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.
