Float valves FM300

FM300 diaphragm float valve is a hydraulic controlled valve. It keeps the water level in the storage tank at a relatively stable level. The float control switch is installed in the water tank when the water level is high and is connected to the basic valve through the pipeline. When the water level rises and exceeds the maximum limited level, the float pilot valve will fully close and the basic valve automatically closed. When the water level drops to the lowest limited level, the float pilot valve will be fully open, the basic valve will automatically open for water supplement until the level in the water storage tank is controlled within the stable ideal range.

If the optional check feature is selected, when the back pressure is generated, the return fluid will enter the air chamber to close the valve to prevent the fluid from back flow.
