WATER-LEVEL SETTING VALVE EN100D
A.WATER-LEVEL SETTING VALVE Structure and purpose
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.

can be selected in the schematic of installation. Recommend to
select the butterfly valve in case of =DN350.
