Features & Benefits

The Bray Series 765 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 ductile iron body is offered in a compact wafer style. When fully open, the valve is full bore, offering no resistance to line media.

Bidirectional Knife Gate Valve Series 765 Features

  • A

    Designed for easy, quick conversion between manual and pneumatic actuation. Featuring a lubricant injection port for continuous, smooth operation with minimal maintenance.*

  • B

    Self-adjusting secondary wiper seal extends gate life and prevents discharge from top of valve.

  • C

    Metal-reinforced, elastomer sleeves provide energized, zero leakage shutoff in both directions.

  • D

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

  • E

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

  • F

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

  • G

    Ample clearance for push-through allows complete gate closure.

  • H

    Compact wafer body allows for easy installation and is drilled and tapped to ASME CL150 flange patterns as standard. Other drilling options available upon request.

  • I

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