A regulator valve having a globe type valve body includes a deformable diaphragm far controlling the fluid flow between the a fluid inlet and a fluid outlet. The deformation of the diaphragm, which is controlled by a pilot pressure introduced into a control chamber within the valve, causes the diaphragm to selectively covers and uncovers a plurality of apertures in a frustoconical baffle to control the flow through the valve. The valve includes a first diaphragm support provided in the control chamber and a second diaphragm support provided on the opposite side of the diaphragm. The second diaphragm support comprises a plurality of concentric cylinders and cross members which form an upper concave surface to correspond to a convex portion of the diaphragm so that the diaphragm is substantially uniformly supported.
