Pneumatic Actuated Polyurethane PU Seated Bi Directional Knife Gate Valve
TEKO Urethane Lined Knife Gate Valves are designed for on-off applications of abrasive slurry and dry abrasive materials. Flanged Urethane Lined Knife Gate Valves are 100% port area and are ideally suited for applications in mining, chemical and food industries. Flanged PU Lined Knife Gate Valves are available in sizes 2-48" (50-1200mm), and grooved end valves are available in sizes 2-12" (50-300mm). Temperature ratings range from -29 to 80º C as standard. The Carbon Steel body is available with a variety of urethane liner compounds suitable for water, oil, food grade, phosphoric acid, and petroleum.
Our PU Lind Knife valves feature a one-piece, cast-in-place bonded liner that provides bi-directional, drip-tight shutoff to either 150 or 250 psi (1030 or 1720 kPa) CWP. Urethane Lined Knife Gate Valves can also provide bi-directional dead-end service to the full pressure rating of the valve. All wetted surfaces are lined with urethane.
The urethane liner is bonded in place to form a continuous liner throughout the entire body, chest, packing chamber and flange face area. The bonding process enhances the mechanical and abrasion resistance properties of the urethane, which creates a robust seat seal in harsh slurry services. The seamless bonded urethane liner extends over the flange face to serve as the valve's flange gasket.
