ABSTRACT:
A valve having a valve body, a valve plug and a deformable valve seat. A generally annular, wedge-shaped space is provided between a portion of the valve seat and a seat support in the valve body. Closing the valve brings the valve plug into single line contact with the deformable seat. Continued closing creates a myriad of line contacts as the seat deforms into the wedge shaped space, occluding any foreign surface particles and bridging surface discontinuities.
