  • Wide flange-face sealing area provides a tight flange-to-valve seal without the use of gaskets.
  • Allows tight shut-off with minimum movement of the seat material to reach the closed position in the center of the seat for ease of actuation.
  • The wide sealing area around the shaft provides a positive seal isolating the shaft from the media.
