Valve and Control
The Cla-Val Model CFC2 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 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.
