Abstract OF THE INVENTION An improvement in a pressure regulator including a valve body, co-engaging seat and poppet, adjustable spring having a bottom plate for co-acting with a low pressure diaphragm member characterized by; for example, a relatively movable seat that includes a centering extension shaft extending to the low pressure side of the valve seat and movable into contact with a ring poppet including a centering and dampening upper protrusion that frictionally encompasses and engages the centering extension shaft of the movable seat to frictionally damp out oscillations of the movable seat and prevent destructive vibrations when gas flow is called for by the regulator. It matters little whether the seat or the poppet is movable and has the delineated centering and dampening structure. Preferably a second spring supports the movable structure.
