Abstract
A pressure regulator includes a hermetically sealed housing that limits the potential for leak paths to atmosphere or exterior to the housing. The regulator includes a dampening arrangement for limiting oscillations during high flow rates. A stem clip secures a poppet assembly to a movable member of the regulator. The stem clip permits radial movement of the poppet assembly to facilitate centering of the poppet assembly relative to a valve seat. The poppet assembly includes a self-tapping poppet to precisely set the opening between the poppet and valve seat irrespective of tolerance stackup.
