A one directional flow valve assembly for a fluid system. The valve assembly is comprised of a valve body having an internal valve chamber in communication with the ambient environment and a valve seat arrangement. The assembly further has a cap structure with means to position and align a sealing member with respect to the valve seat. A flexible elastomeric sealing diaphragm may be utilized and which is under tension when the sealing diaphragm is in a sealing configuration. The sealing member has a peripheral deflection shield to direct ambient fluid through the valve body. A carrier plate structure may be provided to position the sealing member and deflection shield with respect to the valve seat arrangement to operate the valve assembly.
