ABSTRACT:
A fluid closing action dampened shutoff valve for closing a high pressure fluid conductor is formed by a valve body interposed in a high pressure fluid conductor. The valve body contains a valve seat and a normally open valve for seating on the seat and interrupting fluid flow through the valve body in response to fluid pressure above a predetermined value in the conductor. The valve includes a stem slidably supported by and projecting, at one end portion, outwardly of the body. An end plate is secured to the body by posts in axially spaced relation with respect to the valve stem and axially supports a dashpot on the valve stem and a pressure collapsible rod-like pin axially interposed between the dashpot and the end plate.
