Description:
The Bray/VAAS Series 768 is a bidirectional slurry valve, designed for demanding high pressure 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 two-piece bolted wafer style. When fully open, the valve is full bore, offering no resistance to line media.
- 1. Protective stem cover is standard increasing cycle life in hazardous environments.
- 2. J-ring steel-reinforced, elastomer sleeves provide energized, zero leakage shutoff in both directions. Retaining rings included as standard throughout the entire size range.
- 3. In the open position, the energized sleeves shield all metal components from direct contact with the flowing process media.
- 4. Robust gate available in a wide range of corrosion resistant alloys to suit the application.
- 5. Full port design provides unobstructed flow path, extending sleeve life and minimizing pressure drop across valve.
- 6. Ample clearance for push-through allows complete gate closure.
- 7. Optional urethane sleeve (shown) offers additional protection from abrasive line media.
- 8. 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.
- 9. Bottom flush plate with tapped ports provided as standard, allowing for safe discharge of media and easy flush water connection.
