Valve and Control
The Cla-Val Model CF1-C1 Float Control is a float-actuated, multi-
port pilot control which provides non-modulating, two-position, on-off
operation. It is used primarily to operate remotely located Cla-Val
valves requiring three-way or four-way pilot valve operation.
Designed for used in open tanks, this control operates on a minimum
level change of approximately one inch. Maximum level change is
nineteen inches. This level adjustment can be located up to 11
1

feet
from the control by adding float rod extensions.
The float moves freely on the float rod. On rising liquid level, the float
contacts the upper stop and lifts the float linkage to the "UP" position.
As the liquid level lowers, the control stays in the "UP" position until
the float contacts the lower stop. The control then shifts to the
"DOWN" position.
