BULLETINNOVEMBER 202029.00-1ADeZURIK KGN-MSU METAL SEATEDCAST STAINLESS STEELKNIFE GATE VALVESApplicationsDeZURIK KGN-MSU metal seated unidirectionalCast Stainless Steel Knife Gate Valves are designedfor applications in corrosive, abrasive liquid slurry ordry material applications including: Pulp and Paper,Mining, Waste Water, Chemical, Petrochemical,Power, Steel, and others.Design and ConstructionSizes - KGN-MSU Knife Gate Valves are available insizes 2-36" (50-900 mm).Working Pressure – Valve sizes 2-24" (50-600mm)are rated for 150 psi (1000 kPa), valve sizes 30"(750mm) and larger are rated for 100 psi (690 kPa).Body & Gland - The cast one piece lugged body andthe packing gland are available in stainless steel.Gate - The stainless steel knife-like gate is precisionground on all sides with beveled edges to maximizepacking life and seat shutoff.Seat - The integral metal seat provides shutoff thatmeets MSS SP-81 standards.Gate Guides - Rugged gate guides provide supportwhile gate moves up and down.Gate Jams - The jams at the bottom of the bodywedges the gate securely against the seat to assurepositive shutoff.Actuators - The actuator superstructures are heavyduty carbon steel or corrosion resistant stainlesssteel. All valves are furnished with a stainless steelstem. A variety of actuator options are availableincluding: handwheels, chainwheels, bevel gears,and pneumatic cylinders.Flow CapacityRound port design per MSS SP-81 requirementsallows high flow capacity and minimum pressuredrop. A stepped transition port eliminates the cavity,where material can accumulate.End ConnectionsRaised face body has drilled and tapped flangesin accordance with ASME B16.5, 2-24" (50-600mm)or ASME 16.47, 30" (750mm) and larger.www.dezurik.com
