Abstract
A valve assembly for fluid pressure regulation provides freedom from static pressure creep by eliminating distortions and stresses normally introduced to valve parts during assembly of the regulator. A floating valve seat permits normal installation of a valve seat housing in the regulator body with no transfer of stress or distortion to the valve seat. Thus statis pressure creep, normally attributable to micro distortions of the valve seat, is avoided. Options are also provided to install the floating valve seat directly in a regulator body without the valve seat housing.
