Abstract: A valve seat includes a generally cylindrical body that defines a bore extending axially therethrough and has an outer surface. An enlarged diameter portion extends axially from the generally cylindrical body and defines a shoulder surface and an annular surface disposed opposite the shoulder surface; the annular surface is configured to form a seal with a displaceable portion of a valve. An annular notch is formed in the outer surface of the generally cylindrical body, and it extends a distance from a shoulder surface. The annular notch decouples a stiffness of the enlarged diameter portion to thereby increase a radial compressibility of the generally cylindrical body. An annular channel is formed in the outer surface of the generally cylindrical body and is disposed axially below the annular notch. The annular channel is configured to receive a hydraulic fluid to compress radially the generally cylindrical body.

Abstract: A valve seat for a reciprocating pump includes a generally cylindrical body that defines a bore axially therethrough and has a tapered outer surface. An annular surface is configured to form a seal with a displaceable portion of a valve. An annular channel is disposed circumferentially around the generally cylindrical body, and it has a floor surface that is delimited by an upper wall and a lower wall, where at least one of the upper wall and the lower wall forms a non-perpendicular angle with the floor surface.
