Übersicht Designed specifically for cooling tower duty, Marley make-up water float valves provide long life with little maintenance.


Typically, valves are available in complete kits which include valve, float arm and float to fit a specific application.

When installed some trial and error adjustment of the float valve may be required to balance the makeup water with tower operation. Ideally, the float valve setting will be such that no water is wasted through the overflow at pump shutdown. However, the water level after pump start-up must be deep enough to assure positive pump suction.
