EN100D Water-Level Setting Valve is used in the automatic water supply system of a water tower or pool. When the liquid level gets to the set height, it transmits a signal to the pump through a related mechanism to have the pump stop supplying. And when the level is below than the set water level, it starts supply automatically so as to prevent of the water hammer effectively due to the pump's stop and to avoid an extra-high pressure in the pipeline. It features by the sensitive control, high accuracy of level control, not disturbed by the level from the water pressure, tight closure without leak, reliable performance and long duration.
