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.
- Designed for easy, quick conversion between manual and pneumatic actuation. Featuring a lubricant injection port for continuous, smooth operation with minimal maintenance.*
- Self-adjusting secondary wiper seal extends gate life and prevents discharge from top of valve.
- Metal-reinforced, elastomer sleeves provide energized, zero leakage shutoff in both directions.
- In the open position, the energized sleeves shield all metal components from direct contact with the flowing process media.
- Robust gate available in a wide range of corrosion resistant alloys to suit the application.
- Unrestricted flow path with minimal pressure drop achieved through full port valve design for extended sleeve life.
- Ample clearance for push-through allows complete gate closure.
- 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.
- Drain plate with tapped purge ports offered as an option, allowing for safe discharge of media and easy flush water connection.
