Cla-Val CFC2 - Manual (Page 3)

Installation Data
For Controlling Hytrol Valve
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 pressure is used to operate the
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 control may be installed at any
elevation above the valve, providing that the
flowing line pressure in psi is equal to, or
greater than, the vertical distance in 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
this independent source 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 larger, auxiliary Hytrol valves may be
required. Consult factory for details.
Note: We recommend protecting the control
tubing and valve from freezing temperatures.
