Abstract
A springless diaphragm valve and associated diaphragm have increased lifting force for opening the valve. In an embodiment, the diaphragm is a diaphragm assembly of a domed diaphragm having a surface that contacts the valve seat to close the valve, and a biasing member which may also be a domed diaphragm. The diaphragm has a central portion that is attached to the biasing member, for example by a weld. The diaphragm and the biasing member may be nested together, and each may be circular and include a domed portion. The weld is preferably in a central portion of the diaphragm near the apex or geometric center of the diaphragm.
