Abstract
A second stage scuba pressure regulator having a valve seat and a floating piston that is free to travel axially within adjustable limits in relationship to the valve seat. Upon pressurization, the piston is pneumatically actuated to make contact with a valve seat set to a pre-adjusted contact interference. Upon depressurization, the piston is free to retract away from the valve seat to a position of no or minimal contact which will prevent long term deformation of the contacting surfaces.
