ABSTRACT:
The present invention is directed to a valve system which upon disconnection essentially eliminates the release of liquids and vapors to the atmosphere. The invention includes a precision machined poppet and valve seat such that the leading end of the poppet and the end of the valve housing are flush when the valve is closed and such that the sides of the poppet are flush with the surface of the valve seat. Fluids and vapors are eliminated as the valve closes. The valve is not sealed until after closing. The invention is normally used with two flushly abutting valves which close sequentially for the elimination of liquids and vapors.
