Bray - Bidirectional Knife Gate Valve - Series 755

Engineered Durability for Corrosive Industrial Applications

The Bray Series 755 Bidirectional Knife Gate Valve is engineered to excel in managing abrasive and corrosive slurries across diverse applications, focusing on performance and reliability. Its design and robust construction set a new standard for efficiency and durability in industrial environments.Featuring a robust two-piece bolted body configuration, the Series 755 valve ensures structural integrity and simplifies maintenance procedures, enhancing operational efficiency. Similar to the Series 752, the valve utilizes a steel-reinforced molded perimeter seat to achieve zero-leakage bidirectional closure.With sizes ranging from 2" to 24" (50 - 600 mm), the 755 Series offers flexibility to address various application demands. It effortlessly withstands high-pressure environments with pressure rating up to 240 psi (16 bar).To meet specific application requirements, the 755 Series knife gate valve offers a variety of body material options, including CF3M stainless steel, SAF 2205 Duplex, and SAF 2507 Duplex for use in corrosive applications. Furthermore, the Series 755 knife gate valve features a field-replaceable polyurethane bore liner, enhancing performance and providing a cost-effective solution for abrasive applications.
