ABSTRACT:
This invention relates to an improved valve which achieves high reliability through a simplicity of design, a minimum number of parts, a unique valve seat with a two stage sealing action, and at the same time provides a large flow when in the open position, owing to a large cross section opening. The valve features an improved sealing efficiency, in that when in the closed position an increase in pressure on the valve improves the performance of the valve, rather than increasing the likelihood of a leak. The valve is designed to be used in applications which permit the flow of material beyond the valve mechanism to discharge freely, whereby the discharged material activates a float mechanism so as to permit the valve to close when the discharged material reaches a preset level.
