The new KGC-BD Bi-Directional Resilient Seated Knife Gate Valve (photo) features a patented perimeter-seat design that provides bubble-tight shutoff in either direction, even on dead-end service. This gate valve combines a one-piece rubber molded seat with an insert, a spline and a puck that work together to lock the seat securely into the valve body. This unique seat design prevents buckling or dislodging that can occur with other perimeter seat designs, says the manufacturer. In addition, the KGC-BD features the exclusive premium packing system that includes high-performance-packing material options and anti-extrusion segments. Available in sizes from 2–36 in. (50–900 mm), and in a variety to materials, the KGC Bi-Directional valve provides improved sealing, extended packing life and reduced maintenance, says the company. The valve is designed for isolation and on/off applications, and handles clean, dirty, viscous and corrosive liquids, sludge, fibrous slurries, clean and corrosive gases. — DeZurik, Inc., Sartell, Minn.
