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 flanged style. When fully open, the valve is full bore, offering no resistance to line media.
- Stem Cover
Protective stem cover is standard increasing cycle life in hazardous environments.
- Seat
J-ring steel-reinforced, elastomer sleeves provide energized, zero leakage shutoff in both directions. Retaining rings included as standard throughout the entire size range.
- Seat Contact
In the open position, the energized sleeves shield all metal components from direct contact with the flowing process media.
- Disc
Robust gate available in a wide range of corrosion resistant alloys to suit the application.
- Unobstructed Flow Path
Full port design provides unobstructed flow path, extending sleeve life and minimizing pressure drop across valve.
- Push Through Gate
Ample clearance for push-through allows complete gate closure.
- Body
Two-piece bolted flanged body allows for easy maintenance and is drilled and tapped to ASME CL150 flange patterns as standard. Other drilling options available upon request.
- Bottom Flush Plate
Bottom flush plate with tapped ports offered as an option, allowing for safe discharge of media and easy flush water connection.
