Bray - Bidirectional Knife Gate Valve - Series 762

Heavy-Duty Slurry Valve with Advanced SlurryShield Technology

The Bray Series 762 Heavy-duty Slurry Valve, equipped with advanced Bray SlurryShield Technology, ensures exceptional performance and reliability. It effectively prevents media buildup that often prevents other knife gates from reliable isolation and provides bidirectional isolation, showcasing excellence in valve technology and making it the preferred choice for demanding industrial applications.Constructed from durable ductile iron, this valve ensures durability and longevity in harsh conditions. The two-piece bolted flange style body adds strength to the design, while also provide quick and easy maintenance. The two elastomers sleeves provide a replaceable component of the assembly and enable the valve body, gate and topworks to have a long-life cycle. The full-bore design, when fully open, minimizes resistance to line media, optimizing flow efficiency.Standard upper and lower protective stem covers are integrated into all models, prolonging cycle life especially in environments prone to dirt and dust. Moreover, the valve offers various drain containment options including Drain Plate, Drain Pan, and Drain Bucket, providing additional versatility in fluid handling applications.The Series 762 is versatile, suitable for various industries including mining, power, pulp & paper, alumina, chemical, and cement. Engineered to deliver unmatched performance, durability, and versatility, it excels in demanding industrial environments.The Bray Series 762, heavy-duty slurry valve holds several certifications including ATEX, CRN, PED, PE(S)R, TR CU, AND UA TR, ensuring compliance with industry standards and further enhancing its reliability and performance. These certifications highlight its suitability across various demanding industrial applications, making it the ideal choice for handling fluids in industrial settings.
