Abstract
There are provided a fluid flow control valve and an orifice for a fluid flow control valve. The orifice defines two seats against which a diaphragm of the valve can be urged. Each seat defines a particular contour, including one or more channels, slots, and or protrusions that form flow control passages through which fluid flows between the diaphragm and the orifice. The orifice can be configured in either of two orientations so that either seat can be disposed toward the diaphragm. As the pressure differential across the valve increases, the diaphragm is urged more firmly against the seat facing the diaphragm and the diaphragm partially closes the flow control passages, thereby regulating the flow to a substantially uniform volumetric rate. The contours of the two seats can be the same, or each seat can be different to provide a unique controlled flow rate.
