Advanced SlurryShield Technology for Enhanced Durability and Performance
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.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 elastomer sleeves are replaceable components of the assembly and enable the valve body, gate and topworks to have a long-life cycle. Maintenance can be performed 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.
