AIS-Compliant Knife Gate Valves

DeZURIK KGI Iron Knife Gate Valves are designed for on/off and isolation service. They feature a heavy-duty, stainless steel gate that passes through two cartridge-style reinforced elastomer seats. These special elastomer seats provide compression interference fit, providing bi-directional drop-tight shutoff. When the valves are in the open position, the full-port eliminates flow obstructions, keeping abrasive wear to a minimum. The valve’s positive shutoff and reliable performance makes them ideal for many operations such as pump isolation, grit and sludge. They are fully AIS-compliant.

KGI Iron Knife Gate Valves are available in 3-24” (80-600mm) sizes. Valve sizes 3-10” (80-250mm) are rated to 150 psi CWP (1030 kPa) and sizes 12-24” (300-600mm) are rated to 100 psi (690 kPa). The cast iron body and top works have a two-part epoxy coating as standard.
