An access assembly includes an instrument valve housing and a valve assembly disposed within the instrument valve housing. The instrument valve housing includes upper and lower housing sections. The valve assembly includes a centering mechanism, a seal assembly, and a guard assembly. The centering mechanism is configured to bias the valve assembly towards a generally centered position within the instrument valve housing. The centering mechanism includes a base seal member having an annular base and a flange portion. The flange portion includes an arcuate portion configured to adjustably engage first and second surfaces of the instrument valve housing in a sealing relation. The seal assembly is attachable to the centering mechanism. The seal assembly is configured to engage a surgical instrument inserted into the access assembly in a sealing relation. The guard assembly is attachable to the centering mechanism.
