Features & Benefits

The Bray Series 767 bidirectional knife gate valve is designed for demanding slurry applications. Twin elastomer seats and push-through gate design facilitate self-cleaning and prevent media build up.

The durable WCB body is offered in a two-piece bolted wafer style. When fully open, the valve is full bore, offering no resistance to line media.

Bidirectional Knife Gate Slurry Valve Series 767 Features

  • A

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

  • B

    J-ring steel-reinforced, elastomer sleeves provide energized, zero leakage shutoff in both directions. Retaining rings included as standard throughout the entire size range.

  • C

    In the open position, the energized sleeves shield all metal components from direct contact with the flowing process media.

  • D

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

  • E

    Full port design provides unobstructed flow path, extending sleeve life and minimizing pressure drop across valve.

  • F

    Ample clearance for push-through allows complete gate closure.

  • G

    Two-piece bolted wafer body allows for easy maintenance and is drilled and tapped to ASME CL150 flange patterns as standard. Other drilling options available upon request.

  • H

    Bottom flush plate with tapped ports offered as an option, allowing for safe discharge of media and easy flush water connection.
