The
Bray Series 768 bidirectional heavy duty slurry valve is designed for slurry applications in a wafer face to face dimension. The design utilizes twin elastomer seats sleeves and gate designed to facilitate self-cleaning and prevent media build up to ensure bidirectional isolation.
Features
- Protective stem cover is standard increasing cycle life in hazardous environments.
- Fully encapsulated J-ring providing sleeve reinforcement and memory assist, guaranteeing bidirectional zero leakage performance.
- In the open position, the energized sleeves shield all metal components from direct contact with the flowing process media.
- Robust gate designed for slurry applications and available in a wide range of corrosion resistant alloys.
- Full port design provides unobstructed flow path, extending sleeve life and minimizing pressure drop across the valve.
- Two-piece bolted body allows for easy maintenance and is drilled and tapped to a variety of flange standards.
- Optional bottom flush plate with tapped ports allow for safe discharge of media and easy flush water connection.
