ABSTRACT:
A packing resistant valve has a gate rotatably mounted within an angled valve body and an inlet face of the gate defines a concave recess for inducing eddy currents in fluid flow impinging thereon. The eddy currents direct fluid flow away from the valve body, reducing the tendency of the fluid to accumulate within the valve body. Because the valve body is angled, material tends to drain from the body under the influence of gravity. Also, the angled configuration results in the formation of an air pocket within the valve body, precluding packing therein. In one embodiment, a mechanical seal is provided to preclude fluid leakage across the valve stem. In a further embodiment of the invention, a diverter valve assembly is disclosed, which includes a diverter plate for preventing the impingement of fluid against the closed valve disk.
