This adjustable 2-Way Modulating Vertical Float is actuated by the “locked in place” float either pulling the float assembly rod down or floating it up.
This float can be used to control reservoir filling or emptying. When used as a filling level control pilot, it throttles closed as level rises towards set point. When used as an emptying level control pilot, it modulates open as level rises towards set point. The extendable rod is to be balanced by counterweights installed on the lever system according to rod length and system pressure.
