<p>TITLE BIDIRECTIONAL AXIALLY PLIANT PRESSURE ASSISTED SEAT FOR A VALVE A valve seat especially adapted for a high performance butterfly valve is characterized by flexing axially rather than stretching radially when the seat interfaces with a closure member. In the preferred form, a seat has a support member embedded therein to provide restorative forces which tend to urge the valve seat to a predetermined position in response to axial flexing.</p> |
