A rising or falling liquid level in a tank raises or lowers the float ball in the 377 Float Cage.This motion is converted
to force through the rotation of the float rod and lever arm (lever) about the float shaft assembly. The force is
transmitted through the turnbuckle assembly to the lever actuator of a 326L or 322L Lever Valve where it is used
to open or close the valve. Fully immersed in water the float can exert approximately 150 inch-pounds of torque
onto the float arm shaft. The maximum rotation of the float arm shaft is 23°.

INSTALLATION – 377 FLOAT CAGE AND 326L OR 322L LEVER VALVE
(See Information Present on 326L Lever Valves section or Information Present on 322L Lever Valves section for
location of important information on valve). Then see 326L Lever Valve Specification section or 322L Lever Valve
Specification section to determine the performance and physical characteristics of the valve (configuration). See
the 377 Float Cage Specification section to determine the performance and physical characteristics of the 377
Float Cage.
