A weir-type diaphragm valve a valve body with a fluid channel and a weir having a weir sealing portion; and a diaphragm with two or more diaphragm portions, including a diaphragm weir sealing portion at the weir to respond to one force and travel against the weir sealing portion to close the weir-type diaphragm valve and stop fluid flow through the fluid channel, and respond to a second force and travel away from the weir sealing portion to open the weir-type diaphragm valve and allow fluid flow through the fluid channel, a center flexing portion off the weir configured to experience convex and concave flexing extremes when the weir-type diaphragm valve is closed and opened, and an outer sealing portion configured to be fully constrained between components, one of which includes the valve body, when the weir-type diaphragm valve is closed and opened. The diaphragm portions have different characteristics based on different material stresses associated with different functionality that each portion is configured to perform when the weir-type diaphragm valve is closed and opened..
