Abstract
A poppet and seat assembly comprises a poppet having a circular imperforate head portion at one poppet end and has an opposite end adapted for connection with a poppet actuator. The poppet head includes a valve seat interface surface along an outside head surface that tapers upwardly, moving radially outwardly from the head, at an angle in the range of from 8 to 25 degrees. The poppet includes a flange that extends radially around the head and that defines a terminal outside diameter edge of the poppet. The flange includes a tongue that projects axially away from the flange. A diaphragm extends radially around the poppet head and is interposed between the poppet head and the flange to enable poppet head movement relative to the flange. The poppet head, flange and diaphragm are all part of a one-piece construction. The assembly also comprises a circular poppet seat that is positioned adjacent to and opposite from the poppet. The seat has a poppet interface surface that tapers upwardly moving radially inwardly towards a radial axis of the seat in the range of from about 2 to 30 degrees. Together, the interacting poppet and seat surfaces are specifically designed to enable high effici…
