Abstract:
1. A method for operating a gas turbine engine, said method comprising: directing fluid flow from a source into an inlet of a valve; channeling the fluid flow entering an inlet portion of the valve towards an outlet portion of the valve such that a direction of the fluid flow is changed within the inlet portion; controlling the amount of fluid flow entering the outlet portion of the valve by selectively positioning a valve disk coupled within the inlet portion of the valve by a valve disk axle; controlling the amount of fluid flow entering the outlet portion of the valve with a piston assembly that is translatable in a direction that is substantially parallel to a centerline axis of symmetry of the valve outlet portion; and channeling the fluid flow from the inlet portion of the valve through the outlet portion of the valve and into a fluid supply pipe, wherein the valve outlet portion has a substantially right cylindrical shape such that a direction of fluid entering the body outlet portion remains substantially constant therethrough.
