Abstract:
A dump valve for a high pressure fluid line, comprising:a base; a fitting secured to said base and adapted to be interposed along said high pressure fluid line, said fitting defining an internal manifold having an inlet and an outlet adapted for connection to said high pressure fluid line for flow of high pressure fluid having a pressure of at least 500 p.s.i. through said manifold, and a dump port in communication with said manifold; a valve seat in said dump port having a frustoconical surface and an opening in fluid communication with said manifold; a fluid cylinder mounted on said base in movable communication with an extendable and retractable fluid cylinder ram; and a valve member having a frustoconical surface adapted to mate with the frustoconical surface of the valve seat, mounted on said fluid cylinder ram and movable by said fluid cylinder ram between a valve closed position in engagement with said valve seat and closing said opening, and a valve open position in spaced relation from said valve seat whereby high pressure fluid in said manifold is ejected from said dump port upon movement of said valve member to the valve open position.
