A valve component has a body which includes a guide portion, a stem, and a sealing portion between the guide portion and the stem. The sealing portion has a front surface facing the guide portion, a back surface facing the stem, and a recess for a sealing element formed in a periphery of the sealing portion; and one or more passages extending between the back surface of the sealing portion and the recess. ## Claims ### Claim 1 A valve component for a reciprocating pump, comprising: a body, the body comprising: a guide portion; a stem; and a sealing portion between the guide portion and the stem, the sealing portion having a front surface facing the guide portion, a back surface facing the stem, and a recess for a sealing element formed in a periphery of the sealing portion; and one or more passages extending between the back surface of the sealing portion and the recess. ### Claim 2 (depends on 1) The valve component of claim 1, wherein the recess is a channel formed around the circumference of the sealing portion, the channel having a protrusion on each side thereof. ### Claim 3 (depends on 1) The valve component of claim 1, wherein the channel has a profile with a curved portion connected to a linear portion. ### Claim 4 (depends on 1) The valve component of claim 1, wherein the body has a central axis, and each passage has an axis that forms an angle between about 10 degrees and about 80 degrees with the axis of the body. ### Claim 5 (depends on 1) The valve component of claim 1, wherein a sealing element is disposed in the recess. ### Claim 6 (depends on 2) The valve component of claim 2, wherein a sealing element is disposed in the recess and the sealing element is retained within the recess by the protrusions. ### Claim 7 (depends on 5) The valve component of claim 5, wherein the sealing element is formed from a polymer. ### Claim 8 (depends on 5) The valve component of claim 5, wherein a bonding material is disposed between the sealing element and the recess. ### Claim 9 (depends on 1) The valve component of claim 1, wherein each passage is cylindrical, arcuate, or slotted. ### Claim 10 A valve component, comprising: a disc shaped body; a sealing element disposed within an annular retaining recess formed around an outer circumference of the disc shaped body; and a plurality of passages formed from the recess to an outer surface of the body. ### Claim 11 (depends on 10) The valve component of claim 10, wherein a protrusion is formed at an outer edge of the recess. ### Claim 12 (depends on 11) The valve component of claim 11, wherein the passages and the protrusion retain the sealing element within the recess. ### Claim 13 (depends on 10) The valve component of claim 10, wherein the disc shaped body has an axis, and each passage has an axis that forms at an angle between about 10 degrees and about 80 degrees with the axis of the disc shaped body. ### Claim 14 (depends on 10) The valve component of claim 10, further comprising: one or more guides coupled to the body, where in each guide is a member extending radially from a central hub; and a valve stem coupled to the disc shaped body. ### Claim 15 (depends on 10) The valve component of claim 10, wherein the sealing element is formed from a polymer. ### Claim 16 (depends on 10) The valve component of claim 10, wherein a bonding material is disposed between the recess and the sealing element. ### Claim 17 (depends on 10) The valve component of claim 10, wherein each passage is cylindrical, arcuate, or slotted. ### Claim 18 A method of forming a seal on a valve component, comprising: flowing a precursor material into a peripheral recess formed around the circumference of a disc shaped body, wherein one or more passages extend from the recess to an outer surface of the disc shaped body; evacuating gas from the recess through the passages while flowing the precursor material into the recess; and curing the precursor material to form the seal. ### Claim 19 (depends on 18) The method of claim 18, further comprising disposing a bonding material between the precursor material and the recess. ### Claim 20 (depends on 18) The method of claim 18, wherein the disc shaped body has an axis, and each passage has an axis that forms an angle between about 10 degrees and about 80 degrees with the axis of the disc shaped body.
