The Cla-Val Model CFC2 Float Control is a float-actuated, multi­port pilot control which provides non-modulating, two-position, on­off operation. It is used primarily to operate remotely located Cla­Val Valves requiring three-way or four-way pilot valve operation.
Designed for use in closed tanks, this control operates on a
minimum level change of approximately one inch. Maximum level
change of five and one-half inches is needed for full capacity.

Note: We recommend protecting the control tubing and valve from
freezing temperatures.

Represented By:

The float control is mounted at the high water
level in the tank. The remote Cla-Val valve is
installed in the line leading to the tank and is
connected to the float control pilot by tubing.
(Min. 3⁄8" for valves 6" and smaller, 3⁄4" or larger
for valves 8" or larger.)

When line pressu re is us ed to operate th e
valve, tubing connections are made from the
float control pilot to the valve cover, and also to
the inlet side of the valve. An X46 Flow Clean
Strainer must be installed in the inlet side of the
valve. The co ntrol may be instal le d at any
elevation above the valve, providing that the
fl ow in g line pressure in psi is eq ua l to, or

For Controlling Hytrol Valve

gr eat er t ha n, the ver tic al d is tan ce i n feet
between the valve and the float control.

An independent source of air or water may be
used to operate the valve. The pressure from
thi s indep end ent sou rce must constantly be
equal to or greater than pressure at the valve
inlet. The independent source is connected to
the float control pilot in place of the supply line
connected to the inlet side of the valve. If the
Model 100-01 under the control of the CFC2 is
8" or larg er, au xiliary Hyt rol va lves may be
required. Consult factory for details.

Note: We recommend protecting the control
tubing and valve from freezing temperatures.
