APT’s UP-Series knife gate valve is a bidirectional valve deals with flow in both directions, while offering 0 leakage. The u–shape peripheral seat design ensures full-port flow and non-clogging shutoff. ?It is suitable for media such as pulp stock, chemicals, sludge, bio mass, slurry and water.

Body:

  • Integral body structure design, minimizes the possibility of shell leakage.
  • Cavity free bore prevents any particle accumulation in the valve body.

Gate:

  • Beveled knife edge contributes to intensive shear stress, which makes the gate cut through media easily.
  • Gate thickness can be customized according to customer’s requirement.

Seat:

  • U-shaped elastomer seat provides a peripheral seal along the edge of the gate. This non-cavity design eliminates any media accumulation in valve bore.
  • The U-shape design ensures tight seal in both flow directions.
