Claim 0:
1. A seat assembly for a valve, the seat assembly comprising:
a valve body defining a pair of ports, the valve body comprising:
a valve body step defining a recessed valve body sealing surface; and
an annular diaphragm support flange comprising a rounded support surface;

a diaphragm defining a first diaphragm end supported by the annular diaphragm support flange, the diaphragm comprising an annular diaphragm step extending about the recessed valve body sealing surface to form a seal at a second diaphragm end in a closed orientation, the diaphragm comprising:
a diaphragm end wall at the second diaphragm end, the diaphragm end wall defining an inner diaphragm end wall surface and an outer diaphragm end wall surface, the outer diaphragm end wall surface defining the annular diaphragm step between the inner diaphragm end wall surface and the outer diaphragm end wall surface, a head pad extending from the annular diaphragm step to the outer diaphragm end wall surface engaging the recessed valve body sealing surface in the closed orientation; and
