AVK Series 854 Ball Float Valve
The AVK 854 is a series of ball float valves designed to be fitted within a tank or in the
top of a reservoir to control the filling and maintain a pre-determined water level.
The system operates by a float that closes the valve when rising and opens it when
lowering.
The float is made of polypropylene or stainless steel, the internal valve parts are
copper alloy and the valve housing is epoxy coated ductile iron.
Level difference between fully open and fully closed is between 170 mm for DN 50 to
930 mm for DN 300.
