• Knife gate valves are designed for top performance and a long maintenance free lifetime. The stainless steel Knife is precision – buffed for tight shut off. Its knife – like edge cuts through heavy or high viscous fluids. Knife edges are machine chamfered to reduce packing wear. The brass stem nut makes opening & closing the valve smooth and speedy with low torque requirements. Knife valve can be installed between two pipe flanges as wafer type and lug type and can be used in different industries. Because of special design the least contact would be occurs between moveable parts and body. The gate moves up ward and down ward through layers of packing without any touching the body and never collect any heavy viscous fluids or pulverized material and powder on the blade. Knife valve can tolerate heat expansion as hot fluid pass through. Knife valves can be installed at the end of pipe line as a lug. Sealing is Uni-directional acc. to body marking.
