Claim:
1. A fluid control valve comprising: a valve body having a first inner surface defining a chamber having a first axis and a second axis substantially perpendicular to the first axis, the chamber including an inlet and an outlet in communication with the chamber and substantially aligned along the first axis, the inner surface including an elongated seat member substantially aligned along the second axis, the seat member defining a groove, a portion of the body further defining a port in communication with the groove; and a diaphragm member disposed within the chamber for controlling communication between the inlet and the outlet, the diaphragm member having an upper surface and a lower surface, the lower surface including at least a pair of spaced apart elongated members defining a channel therebetween, the diaphragm member having a first position permitting communication between the inlet and the outlet and a second position established by fluid pressure acting directly on the diaphragm member, wherein the elongated members engage the seat member such that the channel is in communication with the groove to define an intermediate chamber in communication with the port, wherein when the diaphragm is in the second position, the upper surface defines a substantially concave surface and the lower surface defines a convex surface.
