66 – Bi-Level Vertical Float


This 4-Way, adjustable, last position bi-level vertical float, is actuated by the float sliding along the rod assembly to either pull it down or float it up, switching the float pilot position. When the float is between the adjustable high and low level stoppers, the main valve remains in its last position.

The float pilot directs flow and pressure between its ports:

  • When the float pushes the upper stopper up, it connects port “P” to “C1” and port “C2” to “V”.
  • When the float pulls the lower stopper down, it connects port “P” to “C2” and port “C1” to “V”.

The extendable rod is to be balanced by counterweights installed on the lever system according to rod length and system pressure.
