Float Control Valves
NOTICE
Hydrau-Flo
®
float control valves are connected to the fuel filling valve via a pilot line. It contains a
float which rises up and stops the bleed and thereby making the spring backed piston in the filling
valve to close and stop filling the tank. The valves are available for both stationary and mobile
applications. These floats and lever floats can be set at varying heights, by simple extensions to
control the level of fuel in the tank when it is full. This float can purge 32cfm of air from the tank
while refuelling at 1000 Lpm (265 USgpm).

The Hydrau-Flo
®
float control valve has a
robust design for use on mobile equipment
which ensures reliable pilot operation of the
Hydrau-Flo
®
fuel filling valve. It also
incorporates roll over shut off protection and
an anti-surge fuel breather vent to prevent
spillage that can occur as a result of vehicle
motion when using “conventional” valves.

is now available in a 1½” NPT mounting
option.
This has being designed for the compact and
underground fuel markets where 1½” NPT
mounting are required.

The newest edition to the Hydrau-Flo
®
float
control range is the float control valve with
breather
option
that
is
capable
of
environmental filtering to 3μm while filling the
tank at 1,000Lpm. The integrated breather
has been engineered on request from major
OEM’s looking to further enhance diesel
engine life in dusty environments. This float
control valve is also available with a shorter
option.
The breather retains all the original anti-surge
functions of the standard green float control
valve but has additional check valves built
into the design to allow venting at 1,000Lpm
and one way breathing to prevent any
contaminants from being drawn into the fuel
tank. For existing systems the float control
valve is able to be retrofitted without
removing the original valve from the fuel tank,
providing a cost effective solution to upgrade
your existing Hydrau-Flo
®
system.
