The FD300 attitude control valve controls the water level in, for example, water reservoirs without the
need for using a float valve or other ancillary controls. The highly sensitive pilot valve and the main
valve are installed outside the water reservoir and the pilot valve senses the hydrostatic water pressure
from the water level in the reservoir. The main valve closes when the maximum set pressure for the
pilot valve is reached and reopens when the water level corresponds to the lower set value on the pilot
valve. The standard version permits filling of a water storage unit. A special version is also available on
request which can be used for both filling and emptying water storage units.
