The Bray Series 767 Knife Gate Valve is engineered specifically for high-pressure slurry applications. Equipped with advanced Bray SlurryShield Technology, this valve excels in abrasive & corrosive industrial environments, ensuring optimal performance. Size range: 3" to 36". Temperature range: natural rubber from -51ºC to 74ºC; EPDM from -54ºC to 120ºC.
Constructed from durable cast WCB, the valve body showcases durability and extended lifespan. Its two-piece bolted wafer style design facilitates easy installation and maintenance while upholding high-performance standards.
Featuring a push-through gate design, the Series 767 ensures bidirectional zero leakage shutoff, making it ideal for use across diverse industries including Mining, Pulp & Paper, General Industry, Power, and Cement. The two eslastomer sleeves are replaceable components of the assembly and enable the valve body, gate and topworks to have a long life cycle. Maintenance can be preformed onsite and customer does not have to send the asset away for extended periods of down time.
Available with natural rubber or EPDM sleeves, the valve provides resistance to abrasion and corrosion. Choose from a variety of gate materials including 316 stainless steel, 2205 duplex stainless steel, and 17-4 stainless steel to meet different pressure rating requirements
Features:
- Fully encapsulated J-ring providing sleeve reinforcement and memory assist, guaranteeing bidirectional zero leakage performance. Designed specifically to operate in higher pressure ratings.
- Designed with ample clearance for gate & media push-through allowing complete gate closure.
A. Stem cover: protective stem cover is standard increasing cycle life in hazardous environments.
B. Sleeves: J-ring steel-reinforced, elastomer sleeves provide energized, zero leakage shutoff in both directions. Retaining rings included as standard throughout the entire size range.
C. Sleeve contact: in the open position, the energized sleeves shield all metal components from direct contact with the flowing process media.
D. Gate: robust gate available in a wide range of corrosion resistant alloys to suit the application.
E. Unobstructed flow path: full port design provides unobstructed flow path, extending sleeve life and minimizing pressure drop across valve.
F. Push through gate: ample clearance for push-through allows complete gate closure.
G. Body: two-piece bolted flanged body allows for easy maintenance and is drilled and tapped to ASME CL300 flange patterns as standard. Other drilling options available upon request.
H. Bottom flush plate: bottom flush plate with tapped ports offered as an option, allowing for safe discharge of media and easy flush water connection.
