Knife gate valve KGD

electricpneumaticisolation

KGD Wafer Style Knife Gate Valve​ AFC Slurry Knife Gate Valve with features of heavy duty, full port elastomer sleeves offering ultimate isolation against heavy slurries. The valves could meet a wide range of abrasion, corrosion, temperature and pressure requirements, which may be used in wet or dry services dealing with large, heavy particles and tramp materials.​ General Applications​ • Mining • Pulp and paper • Steel/Metals • Cement​ • Power​ • Phosphates ​ • Chemical​ Features​ • 100% Isolation; bubble-tight shut-off results in absolutely zero downstream leakage.​ • Double-seated design provides bidirectional flow and shut-off.​ • Unobstructed flow eliminates turbulence, minimizes pressure drop across valve.​ • No seat cavity where solids can collect and prevent full gate closure.​ • Dynamic self-adjusting secondary seal.​ • No gate or stem packing is required, eliminating packing leakage and maintenance.​ • Long lasting lubrication.​ • No metal parts in contact with the flowing slurry.​ • Adaptable frame (yoke) design featuring a top-removal stem nut, can be field modified to an air cylinder or bevel gear in the field without welding. Specifications Sizes Ranges from 3” thru 24” (larger size on request)​ • Pressure Ratings: 3”-16” 150 psi, 18”-24” 90 psi​ • Temperature: Standard Sleeve rated to 80°C, up to 200°C with proper elastomer selection.​ • Materials: Cast Iron, Carbon Steel, Stainless Steel, Duplex SS, or other special alloys.​ • Operation: Manually handwheel or Gear, Electric, Pneumatic or Hydraulic​ • Unobstructed flow eliminates turbulence, minimizes pressure drop across valve
