O Summary:
o When there is no water in the pipe, the bronze valve clack drops down to the full opening position. Air is released from the discharge hole as water coming in, then water can be filled into the pipe immediately.When there isn't any air in the pipe, water comes into the valve, then valve clack goes up to the shut-off position by lifting of the floating ball. These improve water transporting capacity and efficiency of the pipe system, reduce power consuming.
o Air is dissolved into water, and then is released from water continuously when transporting. At this time, the floating-ball drops down, the air is released from the small hole on lever of the valve clack. Or the air gathered at the top of the pipe can lower the water transporting capacity of the pipe system.
o When there is negative pressure in the pipe, bronze valve clack drops down, discharge hole is open, and then the valve draws in the air immediately, so avoid abnormal water supply caused by negative pressure in the pipe.
Unique Design:
o Inside and outside epoxy resin powder coating, no iron exposed.
o Valve pin and lever made of bronze, insure good durability.
o Dust preventing cap fixed upon the guiding bushing,compact design, attractive appearance
