A system including a pressure accommodating assembly having a body with a first side and a second side. The assembly further includes a gas permeable membrane coupled to the body and configured to allow gases to permeate therethrough to thereby move from the first side to the second side. The assembly also includes a pressure relief valve coupled to the body, wherein the pressure relief valve is biased to a closed position to generally block a flow of gases therethrough and is configured to move to an open position when there is a predetermined pressure differential thereacross to allow gases to flow therethrough to move from the first side to the second side. The pressure accommodating assembly is configured to maintain its structural integrity after being exposed to a temperature of about 500&#xb0; C.

Pressure accomodating assembly

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.
