1. A high force gain valve comprising:
- a housing containing a first and second opening, one of said openings being in fluid communication with a fluid source;
a diverter fixed within said housing to divert fluid out said second opening;
a gate disposed within said housing, said gate having a gate body which is movable to open and closed positions, said gate having at least two rods that extend from said gate body and out of said housing; and
actuation means for moving and positioning of said gate between said open and closed positions.

Abstract
A high force gain valve including a fluid inlet, a diverter to absorb pressure and flow forces, a fluid outlet, a moveable gate surrounding the diverter and interposed between inlet and outlet to effect fluid metering, and actuation rods extending out of the pressure region for positioning of the gate. The gate has a beveled sealing edge exposed to the fluid pressure within the housing which permits the gate to be force biased in the open direction. The high force gain valve is designed to reduce tensile and shear stresses so that the valve can be constructed of moderate or low tensile and shear strength materials, such as refractory materials.

11. A high force gain valve comprising:
-
a housing containing a first and second opening, one of said openings being in fluid communication with a fluid source; a diverter fixed within said housing to divert fluid out said second opening; a gate disposed within said housing, said gate having a hollow gate body surrounding said diverter, said gate being movable to open and closed positions, said gate being opposite said second opening such that a sealing edge of said gate surrounds said second opening when said gate is in said closed position, said diverter being opposite said second opening and spaced from said second opening so as to allow an unobstructed fluid flow path through said second opening when said gate is in said open position, said gate having at least two rods extending from said gate body and out of said housing; and actuation means for moving and positioning of said gate between said open and closed positions. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
