An annular valve in which a sealing surface shape of a valve body is optimized, whereby gas pressure loss in the periphery of the sealing surface is minimized and the service life of the valve is extended, wherein the annular valve comprises: a flat plate-shaped valve seat 10 having arcuate passage flow channels 11 of which the opening cross-sections are arcuate in shape; a flat plate-shaped receiving plate 20 that has discharge flow channels 21 and is disposed facing the valve seat 10 across an intermediate chamber 50; valve bodies 30 that are formed into ring shapes corresponding to the arcuate shapes of the opening cross-sections of the passage flow channels 11, are disposed in the intermediate chamber 50, and open and close the passage flow channels 11 by connecting to and separating from the valve seat 10; and spring members 40 that are supported on the receiving plate 20 and elastically urge the valve bodies 30 toward the valve seat 10, sealing surfaces 31 of the valve bodies 30that face the passage flow channels 11 being shaped to exclude at least one element that causes pressure loss with respect to a gas flowing in from the passage flow channels 11 toward the valve bodies30.
