Zusammenfassung:	An elastomeric check valve that may be installed within pre-existing process lines or plumbing that includes an internal bore. In various aspects the disclosed check valve has a stem or stem assembly configured to engage the bore to retain the check valve in place and an elastomeric sealing disk or member. At least a radially outer portion of the elastomeric sealing disk or member is biased or biasable in a selected direction away from a plane that is coincident with a central portion of the elastomeric sealing disk. Fluid may flow through a channel in the stem through a stem assembly and around the elastomeric sealing disk in the selected direction, but is substantially prevented from flowing around the elastomeric sealing disk in a direction opposite to the selected direction, when the check valve is installed within the bore.
