Weir Valves
Below is a list of Weir Valves manufacturers from Irvine, California.
A weir valve is a type of diaphragm valve in which the flow passage includes a weir, or a notch with a horizontal edge through which a substance flows. In the open position, the diaphragm lifts up and allows a substance to flow freely through the valve. Once in the closed position, the diaphragm closes down on the weir, shutting off flow partially or completely.
