ABSTRACT:
A shutoff valve assembly interposed in a fluid line for monitoring fluid flow volume and closing a fluid conductor, in the event of fluid flow volume above a predetermined value. The valve assembly contains a valve seat and a normally open piston valve for sealing with the seat and includes opposing piston rods each slidably supported at one end portion by end caps. The piston valve is normally fluid pressure balanced by equal upstream and downstream rod end surface areas. A plate is secured to the body by posts in axial spaced relation with respect to the downstream end portion of one piston rod for supporting a pressure collapsible rod-like pin in accordance with Euler's law for slender columns, axially interposed between the plate and the adjacent piston valve rod.
