Bray 768 Bidirectional Knife Gate Valve

The Knife Gate Valve Series 768 an engineered solution for heavy-duty slurry handling applications. With a compact wafer face-to-face dimension, this valve provides an efficient and space-saving solution for diverse slurry handling needs, equipped with Bray SlurryShield Technology and can be a direct replacement for conventional knife gate valves.

The valve features a design incorporating twin elastomer sleeves and a self-cleaning gate. The gate is designed to withstand 1.1 times the pressure rating of the valve, ensuring durability in high-pressure applications. Higher pressure ratings can be achieved by utilizing higher yield gate materials such as Duplex 2205 or 17-4PH stainless steel. Sleeves can be replaced onsite enabling the valve to return to service quickly for a long service life.

Certifications include the CRN and PED Category I Module A for Group 2 liquids, ensuring compliance with industry standards and regulations.

The Knife Gate Valve Series 768 provide a guarantee in design and performance, providing effectiveness in heavy-duty slurry handling applications is such as mining, HPAL/POX, Chemical among other industries.

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.
