1. In a high energy loss flow control .[.device.]. .Iadd.valve including a reciprocal valve plug to regulate the quantity of fluid flowing therethrough .Iaddend.for installation in a fluid transfer system where a potentially destructive or noise generating fluid pressure differential exists .Iadd.such that heretofore cavitation, erosion and severe noise will occur.Iaddend.:

  • a rigid structure comprising a stack of members having abutting faces enclosing therebetween a plurality of individual passageway grooves angular between inlet and outlet ends thereof to turn the fluid and provide a substantially longer fluid flow length than the distance between the inlet and outlet ends thereof, and each passageway groove having an effective long length to diameter ratio cooperating with the angular turn-inducing configuration thereof to impart high frictional resistance losses to fluid flow therethrough .Iadd.to a degree that damaging cavitation, erosion and severe noise do not occur in said passageways.Iaddend.; and

    means for compelling flow of the fluid through said passageways whereby potential energy will be dissipated and velocity of the fluid will be controlled.[...]..Iadd., said plug being in slidable contact with said stack of members, said inlet ends being positioned relative to said plug so they are selectively opened and closed to flow by the reciprocal action of said plug..Iaddend.
