Features & Benefits

The Series 746 bidirectional knife gate valve features a one piece urethane liner molded throughout the body and chest providing Class VI shutoff in the most abrasive applications. The liner extends over the front face of the body, ensuring total protection from abrasive media and eliminating the need for additional gaskets. The one piece, durable ductile iron body is offered in a compact wafer style for ease of handling and installation.

Bidirectional Knife Gate Valve Series 746 Features

  • A

    Protective stem cover is standard increasing cycle life in hazardous environments.

  • B

    Live-loaded packing gland extends gate life preventing leakage and discharge from top of valve.

  • C

    Standard one piece ductile iron body with molded urethane liner throughout.

  • D

    Urethane body liner is rated up to 80°C/176°F and completely protects valve body from abrasive line media. (UMP 241 90 Shore, PTMEG-TDI)

  • E

    Unrestricted flow path with minimal pressure drop achieved through full port valve design for extended valve life.

  • F

    Robust gate available in a wide range of corrosion resistant alloys to suit the application.

  • G

    Seat and port designed to be flush eliminating cavities where media can collect and prevent full gate closure.
